“Major Migration” Necessitates Far Fewer Wild Taxes Than Expected.

Serengeti wildebeest migrations may involve fewer animals than previously believed

The “great migration” in East Africa is often estimated to consist of around 1.3 million wildebeest. However, a recent AI analysis of satellite images reveals that fewer than 600,000 animals make this yearly journey across the Serengeti Mara landscape.

This significant migration includes wild zebras and antelopes, as they traverse between feeding and breeding areas in both Kenya and Tanzania, while also evading predators such as lions, crocodiles, and hyenas.

Determining the number of migrating animals is a challenging process, traditionally accomplished through aerial surveys with crew members. These surveys typically cover limited areas, necessitating the use of statistical models to estimate animal density across larger regions.

In contrast, satellite surveys offer a solution to these challenges since a single image can encompass extensive areas, minimizing the chances of double-counting and eliminating the need for metabolic calculations. While manually counting wildebeests over such vast expanses is impractical, AI can aggregate the data effectively. “AI automation enhances count consistency and accuracy,” says Isla Duporge from Oxford University.

In a new study, Duporge and her team developed two deep learning models (U-Net and Yolov8) to identify wildebeest using a dataset of 70,417 manually labeled images. These models were then applied to high-resolution satellite images spanning over 4000 square kilometers, with capture dates of August 6, 2022, and August 28, 2023.

The two AI models returned comparable results: counting 324,202 and 337,926 wildebeests in 2022, and 502,917 and 533,137 in 2023. The apparent disparity between the counts from 2022 and 2023 highlights that the surveys were conducted at different times in August. “[What’s encouraging is that deep learning models with differing methodologies have produced consistent findings,” notes Duporge.

Since the 1970s, earlier estimates of 1.3 million were derived from aerial surveys and have remained largely unchanged. “If we can accurately count all individuals with zero errors based on our results, we estimate the true population size to be around 800,000,” Duporge remarked. “We believe the aerial estimates are inflated, and our count likely reflects a slight underestimation. Some animals may be hidden under trees or outside the survey area, but it’s quite surprising that the count doesn’t exceed 533,137.”

A lower count doesn’t necessarily indicate that the wild population is declining; they may have adjusted their migratory routes. Nevertheless, wildebeests face serious threats, such as habitat loss and fragmentation due to agricultural expansion. Accurately estimating their populations is crucial for implementing effective conservation strategies.

The researchers had previously trained AI models to identify elephants using satellite data, marking the first instance of such a method for conducting individual mammal censuses across large, dispersed populations. The team is now working on a similar approach for detecting and counting African rhinoceroses.

“We should shift towards satellite and AI methods for assessing wildlife populations, particularly for species that inhabit large and diverse landscapes,” suggests Duporge.

Uber Challenges UK Supreme Court Decision on Taxes Affecting Private Employment Competitors

Taxi operators competing with Uber are now exempt from paying 20% VAT on their earnings outside London, following a ruling from the UK Supreme Court in a long-running case.

The court determined that the private employer would not establish a contract with passengers, thereby rejecting Uber’s appeal. This decision was celebrated by the private employer as a “sector victory” after three years of legal challenges.

Uber initiated legal action after a 2021 Supreme Court ruling declared that the driver was classified as a worker.

The company sought a declaration asserting that a privately employed taxi operator had entered into a contract with passengers, a claim supported by the London High Court in 2023.

Initially, that decision required operators to pay a 20% VAT, but the Court of Appeals overturned this after Delta Taxi and Veezu challenged it last July.

Uber brought the issue to the Supreme Court, which unanimously dismissed the case involving the US company on Tuesday.

Nia Cooper, Chief Legal Officer at Veezu, remarked: “This ruling is a triumph for the UK’s private employment sector. The unanimous decision concludes a three-year legal struggle and affirms that operators can select the business models they wish to adopt.”

She added that the outcome would shield passengers from potential fare hikes and lessen the pressure on licensing authorities. “Uber aimed for a declaration that a 20% VAT would be imposed on all PHV fares,” she stated.

“This ruling also illustrates that UK-based companies can stand firm against global conglomerates that attempt to sway the sector through litigation to suit their business frameworks.”

An Uber representative replied, “The Supreme Court’s ruling confirms that different contractual protections apply to individuals booking rides in London compared to the rest of England and Wales. This ruling does not affect Uber’s VAT, which has been upheld in two previous court decisions.”

In a related matter this year, Estonian mobility and delivery startup Volt successfully contested a claim by the UK tax authorities, HMRC, regarding a 20% VAT obligation.

HMRC has since been granted permission by the Court of Appeal to appeal a ruling stating that Bolt is only accountable for VAT on the margin, not on the full fare of the trip.

US Officials Accuse “Silicon Six” of Dodging $278 Billion in Corporate Taxes in a Decade

The “Silicon Six” tech giants in America have been accused of only paying $278 billion (£21.1 billion) in corporate income taxes over the last ten years.

Amazon, Meta, Alphabet, Netflix, Apple, and Microsoft have collectively made $1.1 trillion in revenue and 2.5 trillion in profit during the same period.

Despite this, they have only paid an average of 18.8% in national and federal taxes, compared to the US average of 29.7%, with Silicon Six allegedly involving tax avoidance in their business strategies.

Nonprofit organizations’ analysis showed that the average corporate income tax contribution for these companies fell to 16.1% over the past decade when excluding one-time US repatriation tax payments related to past tax avoidance.

The report also claimed that businesses inflated $820 billion in tax payments by including tax contingencies they didn’t anticipate paying during the same period.

Paul Monaghan, the CEO of FTF, stated, “Our analysis reveals that Silicon Six’s tax avoidance persists within their corporate structure. Their contributions exceed what other sectors like banks and energy pay in many regions globally.”

Monaghan highlighted “active tax practices” and companies’ significant influence on the economy, stressing that they spend millions lobbying the government.

The report points to the impact of tech moguls like Amazon’s Jeff Bezos, Apple’s Tim Cook, and Meta’s Mark Zuckerberg, emphasizing the influence of US tech companies.

Significant tax reductions for these companies reportedly played a pivotal role in discussions with the UK to secure lower tariffs on US exports.

Monaghan explained that much of Silicon Six’s international income benefits from lower tax rates due to tax credits for foreign intangible income. Overseas sales also face reduced income taxes due to lower profit margins and profits booked in low-tax jurisdictions.

Netflix had the lowest tax rate of 14.7% compared to its profit, with Microsoft at 20.4%. Amazon, despite a tax system criticized for profit shifting, had a corporate tax rate of 19.6%, surpassing Netflix, Meta (15.4%), and Apple (18.4%).

An Amazon spokesperson noted that UK revenues, costs, profits, and taxes are all reported and paid in the UK as required.

A Meta representative assured compliance with tax laws across all the countries they operate in, while a Netflix spokesperson stated adherence to relevant tax rules in every jurisdiction.

Microsoft, Alphabet, and Apple have been approached for comment.

Avoiding Taxes in Ancient Rome: Secrets Revealed in 1,900-Year-Old Papyrus Scrolls

In what wasn’t exactly the tax evasion trial of the century – given that it took place in the second century – the charges faced by the defendants were so weighty that they included forgery, financial fraud, and fraudulent slave sales. While tax evasion is an age-old practice, these particular crimes were deemed extremely serious under Roman law, with penalties ranging from hefty fines and lifelong exile to grueling labor and, in the most severe cases, being devoured by wild animals in a practice known as damnatio ad bestias.

The details of the allegations were recorded on papyrus, which was discovered decades ago in the Judean Desert and recently subjected to analysis. The documentation includes preliminary notes for the prosecutor and hastily drafted minutes from the judicial hearings. According to the ancient records, the tax evasion schemes involved document tampering, illicit slave sales, and manumission.

The accused in both tax cases were men. One of them, Gadalius, was the son of a poor notary who had ties to the local administrative elite. In addition to convictions for extortion and forgery, his extensive list of transgressions included banditry, incitement, and four appearances in court for tax evasion before the Roman governor. Gadalius’s partner in crime was a certain Saurus, identified as his “friends and collaborators,” and the mastermind Caper. While the ethnicity of the accused is not explicitly mentioned, their Jewish background is inferred from their biblical names Gedaliah and Saul.

This ancient legal saga unfolded during the reign of Hadrian, around the year 130 AD or possibly before 132 AD when Simon Bar Kochiba, the leader of the Messianic rebels, launched a large-scale uprising, marking the third and final conflict between the Jewish people and the Empire. The rebellion was brutally suppressed, resulting in hundreds of thousands of casualties, mass expulsions of Jewish communities, and the renaming of Syria and Palestine by Hadrian.

Anna Dolganov, a historian of the Roman Empire at the Austrian Archaeological Institute who deciphered the scroll, remarked, “The papyrus sheds light on the Roman authorities’ suspicion of their Jewish subjects.” She pointed out that there is archaeological evidence of a coordinated effort during the Bar Kochiba rebellion. “It is plausible that individuals like Gadalia and Saurus, who sought to subvert Roman rule through tax evasion, were involved in the uprising’s planning,” Dr. Dolganov suggested.

In the latest edition of Tyche, an ancient journal published by the University of Vienna, Dr. Dolganov and three colleagues from Austria and Israel present court proceedings as case studies. Their research unveils how Roman institutions and imperial law influenced the administration of justice in an environment with relatively few Roman citizens.

“This document provides intriguing and valuable insights into the slave trade in this region of the empire,” noted Dennis P. Kehoe, a classicist at Tulane University not involved in the study. “The allegations may involve the Jews owning slaves.”

The exact date and location of the papyrus’s discovery remain uncertain, but Dr. Dolganov suggested it was found by an ancient Bedouin dealer in the 1950s. She suspected Nahal Haver, a steep canyon west of the Dead Sea where Bar Kochiba rebels sought refuge in a cave hid along the natural fault line of a limestone cliff. In 1960, archaeologists unearthed documents from the era in one of the Jewish hideouts, with more discoveries made since then.

A 133-line irregular scroll, initially misclassified, went unnoticed in the Israeli Antiquities Authority archives until 2014 when Hannah Cotton Parietl, a classicist at the Hebrew University of Jerusalem, identified it as being written in ancient Greek. Given the complexity and exceptional length of the document, a team of scholars was assembled to conduct detailed physical examinations and cross-referencing with historical sources.

Deciphering the papyrus and piecing together its intricate narrative posed a significant challenge for Dr. Dolganov. “The text features small, densely packed letters and highly rhetorical Greek replete with technical legal terminology,” she remarked. Unlike more straightforward documents such as contracts, there were no standardized templates for translation ease. “The fact that we only have the latter half of the original text further complicates matters,” Dr. Dolganov added.

Researchers speculated that the tax evasion scheme aimed to circumvent official scrutiny. This necessitated meticulous detective work to decipher the sequence of events. “I had to adopt the Roman fiscal authorities’ perspective to grasp the text’s nuances,” Dr. Dolganov explained. She also had to step into the accused’s shoes to understand the rationale behind tax fraud in the remote fringes of the Roman world.

The ancient stratagems resonate with contemporary tax experts. A German legal expert relayed to Dr. Dolganov that the subterfuges of Gadalius and Saurus mirrored present-day practices of tax evasion, such as asset shifting and fictitious transactions. The Roman interrogation methods aligned closely with modern-day investigative custody for financial crimes, marked by intimidation and frequently rigorous questioning.

A Princeton University classicist unaffiliated with the project, Brent Shaw, remarked:

The cases against Gadalius and Saurus were bolstered by intelligence provided by informants who betrayed them to the Roman authorities. Interestingly, the text implies that the informer might have been none other than Saurus himself, who implicated his partners to shield himself from an imminent financial scrutiny. The most plausible scenario posits that Saurus, a Jewish resident, orchestrated the pseudo-sale of several slaves to Chareas, a neighbor residing in the adjacent Arabian province, as per Dr. Dolganov’s interpretation.

By selling slaves across provincial borders, Saurus sought to obfuscate assets from scrutiny. While physically present in Saurus’s custody, the slaves, undocumented in Arabia, evaded declaration by Chareas. “Effectively, the slaves vanished on paper from Judea and never materialized in Arabia, eluding Roman oversight,” Dr. Dolganov noted. “This ensured that no further taxes were levied on these slaves.”

The Empire implemented a sophisticated system for monitoring slave ownership and collecting various levies, including a 4% tax on slave sales and a 5% duty on estates. “To emancipate empire-owned slaves, detailed documentary evidence of current and prior ownership was mandatory,” Dr. Dolganov elucidated. “Any missing or dubious documents would trigger an inquiry by Roman administrators.”

In an attempt to conceal Saurus’s double-dealings, Gadalius, the son of a notary, allegedly fabricated bills of sale and other legal documents. When authorities detected irregularities, the defendant purportedly bribed the local municipal council for protection. During the trial, Gadalius shifted blame onto his deceased father for the forgeries, while Saurus implicated Chaireas in the document tampering. The papyrus does not provide insights into their motives. “The rationale behind men risking forgery to liberate slaves without legitimate documentation remains a mystery,” Dr. Dolganov mused.

One conjecture posits that by orchestrating fake slave sales followed by manumission, Gadalis and Saurus may have been adhering to a Jewish religious mandate to free those enslaved. Alternatively, there might have been a profit incentive in capturing individuals across borders, potentially entrenching them as free Romans after freeing them from “enslavement.” Or Gadalia and Saurus might have engaged in human trafficking, a possibility that is as speculative as it is fraught with implications, Dr. Dolganov emphasized.

One aspect of the trial that struck Dr. Dolganov was the prosecutor’s professionalism. Employing sophisticated rhetorical strategies reminiscent of Cicero and Quintilian, the prosecutor exhibited a mastery of Roman legal terminology and concepts in Greek. “Here, on the edge of the Roman Empire, we witness a highly skilled legal practitioner steeped in Roman law,” Dr. Dolganov remarked.

The papyrus does not reveal the final verdict. “If a Roman judge deemed these men as incorrigible criminals deserving execution, Gadalius, as a member of the local elite, might have met a more merciful end through decapitation,” Dr. Dolganov suggested. “In any case, it beats being torn apart by a leopard.”

International Monetary Fund (IMF) calls for consideration of balancing the effects of AI with profit and environmental taxes

The International Monetary Fund (IMF) suggests that governments dealing with economic challenges brought about by artificial intelligence (AI) should look into implementing fiscal policies such as taxes on excessive profits or environmental taxes to offset the carbon emissions linked to AI.

The IMF highlights generative AI, which enables computer systems like ChatGPT to create human-like text, voice, and images from basic prompts, as a technology advancing rapidly and spreading at a swift pace compared to past innovations like the steam engine.

To address the impact on jobs due to AI, the IMF proposes policies like a carbon tax considering the environmental effects of operating AI servers. The IMF emphasizes the importance of taxing carbon emissions from AI servers to incorporate environmental costs into the technology’s price.


The IMF report released on Monday highlights the significance of taxing carbon emissions associated with AI servers due to their high energy consumption and the potential to impact data centers’ electricity use. Data centers, servers, and networks currently contribute up to 1.5% of global emissions, according to a recent report.

In addition, the report cautions that introducing AI could reduce wages, widen inequality, and empower tech giants to strengthen their market dominance and financial gains. It recommends higher taxes on capital income, including corporate taxes and personal income on dividends, interest, and capital gains, to address these challenges.

Furthermore, the report stresses the need for governments to prepare for the impact of AI on various job sectors, both white-collar and blue-collar, and suggests measures like extending unemployment insurance, targeted Social Security payments, and tailored education and training to equip workers with necessary skills.

To overhaul the tax system and introduce new taxes reflecting real-time market values, the IMF recommends leveraging AI’s analytical capabilities. While cautioning against universal basic income due to its high cost, the IMF suggests considering it if AI disrupts jobs significantly in the future.

Ella Dabra Norris, deputy director of the IMF’s Fiscal Affairs Department and co-author of the report, encourages countries to explore the design and implementation of systems like UBI if AI disruption intensifies.

Jeff Bezos could potentially save $600 million in taxes by relocating to Florida.

Billionaire Jeff Bezos and his fiance Lauren Sanchez saved $600 million in taxes just by moving to Florida.

The accounting windfall resulted from the $2 billion sale of Amazon stock.

Bezos, 59, who is in a three-way race with Microsoft’s Bill Gates and Tesla’s Elon Musk to become America’s richest man, announced in November that he would be leaving Seattle, where he has worked for 30 years. –This is what he said on the outside: in an instagram postto be closer to his parents, and his Blue Origin rocket is launched at Cape Canaveral.

“I’ve lived in Seattle longer than anywhere else and have so many great memories here. This move is both exciting and an emotional decision for me. Seattle, you will always be my It’s a part of my heart,” he wrote.

But on Tuesday, Financial News Network CNBC provided another clue In response to his move, Washington two years ago introduced a new 7% capital gains tax on the sale of stocks and bonds worth more than $250,000.

However, Florida does not tax income or capital gains.

Since 1998, Bezos has been involved in projects such as his philanthropic project Blue Origin, new homes on Miami’s “billionaire bunker” island Indian Creek and a $500 million, 417-foot home, the newspaper reported. The company has reportedly sold billions of dollars in Amazon stock to raise money for splashy acquisitions such as Amazon. Megayacht Col.

Last year, after the new tax was introduced, Bezos halted sales of Amazon stock until he notified the U.S. Securities and Exchange Commission that he planned to sell 50 million shares by January 31, 2025, at a current value of That’s equivalent to $8.7 billion.

With the first $2 billion tranche last week, Bezos saved $140 million in taxes he would have paid to Washington state. If Amazon stock continues to rise, total sales over the next two years will be about $610 million or more. This savings is enough to cover Kuro’s expenses.

The cost of relocating to Miami was in itself daunting for the couple, who have so far purchased two homes in Indian Creek, near the mansions of quarterback Tom Brady, Ivanka Trump and her husband Jared Kushner. It has invested $47 million. Investor Carl Icahn.

Real estate brokers in Miami say Mr. Bezos will likely demolish two homes and build new ones. He is also said to be considering other properties on the island, which is itself a municipality and has a mayor.

Kobi Karp, an architect who has worked in Miami “since the days of Miami Vice and Scarface,” told Bloomberg that the island’s biggest draw is privacy. paul george, History Miami Museum He told the media that the island was “inhabited only by very wealthy people, billionaires.”

Karp added: “We’re not going to lose hundreds of millions more.”

But Bezos’ personal real estate projects may not fully account for the costs involved in moving the billionaire, his fiancée and their support staff across continents. Shortly after Bezos announced the couple’s move to Miami, Amazon announced it was looking for 50,000 square feet of office space near Brickell.
