SPACEX'S BUMPY RIDE ON THE STOCK MARKET MAY GET BUMPIER

The first lockup on SpaceX shares is set to expire today. Employees and other company insiders who were prevented from trading stock after SpaceX's IPO will now be able to do so. Lockups prevent shares from flooding the market and driving down their price after an IPO. More than double the current supply that can be traded will be made available, which may further depress the price.

SPACEX IS SET TO ACQUIRE 130,000 ACRES OF MARSHLAND IN SOUTHERN LOUISIANA

SpaceX is close to finalizing a deal to acquire about 130,000 acres along the northern coast of the Gulf of Mexico. The deal is expected to be officially announced later this month. The site, known as Pecan Island, is an 18-mile stretch of marshland. It became available as part of a legal settlement that resolved dozens of lawsuits blaming ExxonMobil for pollution and coastal land loss.

DRUG DISCOVERY HAS NO MAGIC WANDS

AI is set to transform human health. However, it will not be a magic wand: we don't understand human biology well enough for a clever enough reasoner to find the cures hidden in what we know. Aimed at biology we barely understand, AI will mostly help us generate failures faster. The path to real cures is to measure biology in the right way and use AI to derive novel insights from those measurements.

LLMS REWARD EXPERTISE

The most important skill in prompting is expertise in the domain you're prompting for. The domain knowledge makes you better at using AI because you have a sense of what a good solution might look like and can therefore write better prompts. The usefulness of domain knowledge suggests that human expertise will continue to be useful even as models get stronger.

THE ENDGAME OF VERTICAL INTEGRATION

Model labs and agent labs are converging. Model labs continue to develop first-party applications that compete with their customers, while agent labs are starting to train models. The gains from co-designing models with harnesses is why agent labs need to move into model training. The challenge is for agent labs to offer the best intelligence per dollar at margins that the model labs can't match.

WHAT ARE COMPANIES GETTING FOR ALL THAT AI SPENDING?

The cost and benefits of AI are difficult to weigh. There are now thousands of models, and there is no consensus around how much energy a token requires, which model is best to perform a given task, or how many tokens it should take. The Linux Foundation established the Tokenomics Foundation in June to create common parameters for AI providers to disclose. Being able to measure the costs and benefits of AI will help researchers understand how AI is going to change everything.
