In that context, I wouldn't expect an idiot (of which there has always been far too many in this industry) to change their behaviour in a post-ai world. They were always out of line & continue to be.
Fwiw, a non-technical employee in my workplace has begun submitting ai-generated prs to internal repos I maintain & they're of excellent quality, with review feedback graciously received & expediently addressed, so this isn't a matter of the idiots not being technical, it's an attitude problem.
Moreover, as these tools become more expensive, people with money to blow on tokens will be able to drown maintainers that don’t have enough token-cash to help them deal with it. People see this as mostly a matter of time and energy, but I reckon it will soon be a financial issue.
I think we'll need to revert to artificial barriers such as bonds, e.g., if you want to do a PR to my repository you need to pay a 10 dollar bond. If the PR is good and I want future PRs, you keep your bond. If it's slop and spam, I get 10 dollars for my time.
