I “agree” with your “sentiment”.

But I can’t shake the feeling that discussing this stuff is indeed void on the AI era. I considered my self a JS/TS/React expert dev, derivate, state duplication, url as a source of truth…

All of these points feel void now, I have not checked/cared how my React code looks like in months now. I only care about more high level stuff like schema definition and overall wiring.

You sound like me before I tried Fable.

You sound like most people I know that only have a Claude subscription. GPT-5.6 is so much better bang for the buck.
