As an individual, his LLM carbon footprint and money used to purchase AI services aren't going to matter at all. But him being one of the world's highest profiled software engineers who's openly using these tools is very good publicity for them.

I think the anti ai crowd has been focusing on the slop angle too much, the horrible malpractice of these companies is the real problem imo. If it really is only slop it will die out by itself.
