"Overton window"? It's just developers being obtuse, short-sighted and slow.
It was obvious in 2023 and it is obvious now yet we still have people in denial even today. These people need AI to take over the world and threatening them with eternal suffering before they will change their minds even a bit.
May I ask why you care so much? Some people like hand-coding, they are free to do whatever they want, stop being so weirdly angry and controlling about what people do/how they do it.
