I think it's referring to Linus using AI to develop a python GUI in January for a personal pet project (AudioNoise).

It was the beginning of this cognitive outsourcing that's led to him telling people with entirely legitimate concerns (e.g. that LLM output can't be copyrighted, so it can't be licensed as GPLv2) that he'd ignore them all and to "fork it or walk away", to people who have developed the kernel for many years of their lif.. To now - hiding LLM commits to obfuscate kernel commit info.

I respect and appreciate Linus, but the recent developments highlight a larger (and old) problem of Linux - a single point of failure in Linus and the BDFL attitude. He'll eventually leave the kernel in some way, and while there are drafts and proposals for a succession plan - none have been seriously considered to the point of any action by Linus. He remains the kernel BDFL, and Linux kernel development remains neither a meritocracy nor a democracy.
