I mean it depends, right? There are several technologies out there that are fantastic because they are less annoying, have fewer footguns, easy to debug, easy to read, good tooling (docs, tests, package management), and respect the programmer's sanity. Is it wrong to only want to work with such systems? If some company rejects me because I'm a tech stack fanboy without asking and understanding why I care about the stacks that I do, that means they don't respect my sanity. Hate to say it, but most "boring" technologies with a legacy from, say, pre-2000-ish, cared zero about those things.

So, great. Buh-bye.

Nb: many technologies post-2k also don't care about those things. So yeah, don't be shiny new on those either.
