This sort of angry post, with many demands "attitude adjust" "delegate" and invectives "close-minded" "lazy" never appeared for any other technology shift. React devs never posted like this about jQuery devs. Mobile app devs never posted like this about mobile web devs. Yet tons of AI users post like this about non-AI-using devs.

Is it some kind of fear or doubt? It's a strange phenomenon.

Like for example I strongly believe Typescript is better than Javascript and needs to be used instead for any serious project. But if someone says they don't like it, I cannot imagine myself writing a post like yours about it. First of all I don't care what they use, but second of all if I really wanted to convince them it would not look anything like this. Your post and many like it reads like anger and condescension and incredulity.

He's drunk the kool aid and forgotten that some of us have been working in this industry for decades and got along just fine without AI, while he's busy debugging his technical debt and getting sued for leaking customer data I'll just be over here quietly enjoying coding for customers who like dealing with human beings and not black box robots.
