Linus seems to be taking a perfectly pragmatic approach, given that AI is not going away short of WW3.
I can imagine some individual sub-system maintainers introducing various AI-roadblocks though.
I also expect this to be increasingly addressed (in general) with model & tooling improvements, giving more weight to higher quality reports and MRs, and more respect for project rules and processes. A mix of soft and hard gates, CLAs, improved early automated bug report & patch reviews and other CI gates.
It may be that he/they have significant competency in this domain, just not publically or under this name/pseudonym.
I’ve personally made contributions under pseudonyms just to avoid employer paperwork/approvals, for projects that I’d rather not have my real name attached to, and for sharing in potentially hostile communities.
I’ve also developed software internal to companies that has never been released publicly.
In short … he doesn’t need to prove his prior credentials to you, me, or anyone. He may have some, he may not.
We can legitimately critique what he/they have done in this project all we like though.
