Meta’s Mark Zuckerberg posted a letter yesterday focused mostly on the potential for so-called “personal superintelligence.” He said that while AI will inevitably cause societal change akin to the agricultural revolution, allowing for discoveries that “aren’t imaginable today,” the real frontier will be at an individual level.

Meta is shifting how it plans to ensure widespread access to superintelligence, a suggestion that the company’s most advanced AI may remain closed so that Meta can stay in the driver’s seat.
