Trump Bets Big on AI — With Almost No Details

The US president has announced an AI czar and an "AI Force," but offered little substance beyond a prediction that AI could reshape a quarter of the American economy.

On Saturday, Donald Trump announced two new institutions — an "AI Force" modelled on the Space Force he established during his first term, and a forthcoming AI czar whose appointment he said would be revealed "in the near future" — without providing a budget, a mandate, or a timeline for either. The social media post in which he made both announcements ran to several hundred words, yet contained almost no policy architecture. What it did contain was a prediction striking enough to anchor the entire debate: Trump claimed that artificial intelligence could eventually account for as much as 25 per cent of United States GDP. The announcements appear to be a partial concession to critics, including many within his own Republican Party, who have called for regulatory guardrails as industry figures warn about AI's potential threat to public safety and, in some forecasts, human existence.

Yet Trump simultaneously dismissed those concerns as a "hoax," placing AI anxiety alongside Russian election interference and climate change in a list of what he characterised as politically motivated alarmism. That rhetorical contradiction — creating oversight bodies while denying that oversight is needed — has left analysts uncertain about the administration's actual direction. Underlying the announcement is a geopolitical calculus that enjoys broader political support: the fear that China will surpass the United States in AI capability if American development is slowed. That competitive logic has made the White House reluctant to impose binding restrictions, even as the European Union's AI Act has come into force and governments from Seoul to São Paulo are drafting their own frameworks.

Buffett Steps Down After 60-Year Reign

In 1965, Warren Buffett acquired a failing New England textile mill for a modest sum. Six decades later, that mill — Berkshire Hathaway — is valued at $1.1 trillion, a figure that makes it one of the largest corporations on Earth. At 96, Buffett has now resigned as chairman, passing the role to his son Howard, who has served as a board director since 1993. Greg Abel, appointed chief executive nine months ago, retains control of strategy and capital allocation. The transition is structured rather than abrupt. Howard's designated responsibility is preserving the firm's culture, while Abel drives operational decisions — a deliberate division that analysts say reflects Buffett's trademark long-term thinking.…

British TV Fights to Survive the Streaming Age

In the summer of 2025, three of Britain's most recognisable broadcasters announced cuts that would have been unthinkable a decade ago. Channel 4 is eliminating 28% of its workforce — the deepest redundancies in its 43-year history. The BBC's new director-general, former Google executive Matt Brittin, is pushing through up to 2,000 job losses, while ITV has agreed to sell its broadcasting arm to Sky for £1.6 billion. The arithmetic behind the crisis is unsparing. Silicon Valley platforms — Google, Meta, and Netflix among them — are forecast to capture nearly $50 billion, roughly two-thirds of all UK advertising revenue, by 2028.…
  • Can any publicly funded broadcaster survive in a world dominated by global streaming platforms?
AI is the next Industrial Revolution, or Internet, but will be even larger and more impactful, possibly as much as 25% of our Country's GDP.

  1. Not only Trump announce an AI Force, but he also promised to name an AI czar in the near future.
  2. Hardly Buffett stepped down as chairman when analysts began debating whether Berkshire Hathaway's legendary culture could survive.
  3. Never before a United States president claimed that AI could account for as much as 25 per cent of GDP.
  4. Not only the BBC facing thousands of job losses, but ITV has also agreed to sell its entire broadcasting arm to Sky.
  5. Seldom British broadcasters have confronted cuts on this scale, with Channel 4 eliminating 28 per cent of its workforce.
  6. Hardly Buffett written his shareholder letter when the financial world began reflecting on his remarkable 60-year tenure.
IIIDEPENDENT PREPOSITIONS
Complete each phrase with the correct preposition. All from today's articles.
  1. Trump's AI Force is modelled ___ the Space Force.
  2. The EU's AI Act has come ___ force.
  3. Governments from Seoul ___ São Paulo are drafting frameworks.
  4. Howard Buffett has served ___ a board director since 1993.
  5. Channel 4 is eliminating 28% ___ its workforce.
IVCRITICAL THINKING
Warren Buffett built Berkshire Hathaway on patient, long-term thinking, yet the media industry's collapse suggests that even well-established institutions can be overtaken by forces no amount of patience can reverse. At the same time, Trump's AI announcements prioritise speed over structure. What do these two stories together suggest about when patience is a virtue and when it becomes a liability?
