THE IDENTITY CRISIS AT ELON MUSK'S CHAOTIC AI OUTFIT

One of SpaceXAI's goals is to get Grok to catch up to Anthropic's Claude. The company recently released a new coding tool and beefed up its sales team, but it is still running behind its competitors in many measures. It has been in a state of chaos over the past few months, making it difficult for outsiders to see where Elon Musk imagines the company heading. Many insiders considered the company unprepared for the scrutiny that comes with being a company, and now that it is public, SpaceXAI has less room to maneuver.

GOOGLE GEMINI LAUNCH DELAYED AS TECH FALLS SHORT OF INTERNAL GOALS

Google has months behind schedule on delivering Gemini 3.5 Pro. The company has been taking its time trying to improve its capabilities, particularly in coding. The delay has frustrated Google engineers, AI researchers, and managers, many of whom are concerned that the company risks losing an edge. The model is currently being tested with partners, and Google is productively engaged with the US government on model testing and broader frameworks.

AI AND A BRAIN IMPLANT RESTORED A PARALYSED MAN'S MOVEMENT AND TOUCH

Researchers restored hand movement and a sense of touch to a man paralyzed from the chest down using technology that partly rewired his nervous system. The 'double neural bypass' system combines a brain-computer interface, AI, and electrical stimulation of the spinal cord and brain to produce long-lasting changes. Many of the improvements were still present more than two years after treatment. The researchers are now planning larger trials and are testing the system for other conditions, including stroke.

THE FDA APPROVES A NEW PILL TO SLASH CHOLESTEROL LEVELS

The FDA has approved a pill that can lower cholesterol levels far beyond what can be achieved with statins. Made by Merck, enlicitide works by inhibiting a protein known as PCSK9. Its list price is $315 for a 30-day supply, and it will be available in a few weeks. Similar injectable drugs have been shown to reduce the incidence of heart attacks, strokes, and cardiovascular deaths by 20% in high-risk people - Merck is now conducting studies to see if its pill has the same effect.

WHAT CAN WE LEARN FROM BUN'S RAPID RUST REWRITE WITH AI?

Bun was rewritten from Zig to Rust using Fable. A full rewrite would usually take too long, but the AI tool allowed it to be completed in 11 days. The project cost $165,000 with API pricing, consuming 5.9 billion uncached input tokens, 690 million output tokens, and 72 billion cached input token reads. The rewrite demonstrates how AI can now be cost-effective for codebase migrations when projects are well-engineered.
