After 15 years building Apple into a $4 trillion institution, Tim Cook is handing the keys to John Ternus, a mechanical engineer who has spent a quarter century shaping the products Cook sold. The transition says as much about where Apple has been as where it is going.
On April 8, Elon Musk listed seven models in simultaneous training on Colossus 2 and captioned the post "Some catching up to do." The cluster burns 400 megawatts, runs on an estimated 550,000 NVIDIA Blackwell GPUs, and is training a 10-trillion-parameter model. The question is whether scale alone can close the gap.
Six publicly available frontier models are clustered within 1.3 percentage points on the industry's most-cited coding benchmark. Meanwhile, a withheld model just scored 93.9% on the same test. The measurement system isn't broken - it's being gamed at two levels simultaneously.
Claude Mythos Preview can autonomously find and exploit zero-day vulnerabilities in every major operating system and browser. Rather than shelve it, Anthropic has handed it to a coalition of 50-plus firms under Project Glasswing. The strategy is defensible. Whether it holds depends on who else is building the same thing - and Washington's posture toward the company that built it.
In 2025, just ten companies absorbed 41% of all U.S. venture dollars - a concentration level with no precedent in a decade. The headline figures flatter a market that is quietly contracting at its base, where deal counts have hit a six-year low and seed funding is falling. The question is not whether AI deserves capital. It is whether this degree of gravitational pull leaves room for anything else.
Global AI spending is on track to hit $2.52 trillion in 2026, yet 95% of task-specific enterprise AI deployments deliver zero measurable P&L impact. The problem isn't the technology - it's where the money is going.
A federal judge blocked Perplexity's Comet agent from Amazon's site on March 10. Two days later, the company unveiled Personal Computer, a persistent AI agent running locally on a Mac mini. The two events are not coincidental - they define the strategic dilemma at the center of the agentic web.
On February 3, 2026, $285 billion of market capitalization vanished from software and financial stocks in a single session. The trigger was an AI agent announcement. The governance response has barely begun.
NVIDIA's Vera Rubin platform, announced at CES 2026 and entering production this year, promises 10x lower inference token costs and 5x per-GPU compute over Blackwell. This is not an incremental upgrade. It will fundamentally reshape who can afford to build frontier AI.
