It's really interesting how some people seem to take skepticism, disinterest, disappointment, apathy about AI almost personally. I would think if the tools really are so game-changing just let things be, as the cold hard reality will fall upon this guy and he will be left without a job unless he adopts these tools.

I think the real cold hard reality is that these AI tools can't and won't be the revolution they're purported. There's too much messiness in everyday software engineering jobs: tribal knowledge, dismal documentation, company politics, a toxic co-worker, a manager almost seeking to make the project fail, lack of code consistency, apathy, etc.
