The author of that post Nolan is a pretty interesting guy and deep in the web tech stack. He’s really one of the last people I’d call "tribal", especially since you mention React. This guy hand-writes his web components and files bug reports to browsers and writes his own memory leak detection lib and so on.
If such a guy is slowly dipping his toes into AI and comes to the conclusion he just posted, you should take a step back and consider your position.
I really don't care what authority he's arguing from. The "just try it" pitch here is fundamentally a tribalist argument: tribes don't want another tribe to exist that's viewed as threatening to them.
