> You're so concerned with development speed, yet you're rewriting the same thing in a new framework every 2 years.

I think that meme gets thrown around a lot, and it used to be true, but the framework churn of JS has largely stopped at this point. A lot of us (me included) have been just using the same stack for several years now.

Sure, React has evolved since 2015/2016 (e.g. the move to function components and hooks) but the old code still runs, with minimal to no changes. Patterns and best practices have largely been established. You can entirely avoid the bleeding edge stuff and still be productive.
