Au contraire. Web development has always been fun, unless you add all the crap mentioned in TFA. If you feel you need all that stuff to feel grown up, then I guess LLMs help a lot. But the barometer hasn't changed: make something that people love.
So you’re skipping any sort of a build pipeline? You’re not going to bundle, so no code minification? You’re going to skip tests ? And everyone who uses these things just does them to “feel grown up” and not for any particular benefit or purpose beyond that?
If you spend so much time on the cumulation of product-adjacent activities that you don't make a good product, then their cumulative value to you was negative.
But I do, personally, love a good build system. The value is extremely high and it only takes 10 minutes to set one up.
