Basically every wheel has been reinvented (usually worse than the thing they're trying to replace) multiple times, just because.

On the front end every tool now relies on and is installed by npm/nodejs and will require 90 other packages, and will be replaced yet again in 6 months time.

Basically, web developers got sick of "they're not real programmers, they just write scripts" and made their own ridiculous tool chains to solve problems they themselves created.

Edit: forgot to add, every developer who knows what bash is feels like they're a qualified system admin now because aws has an api so ops staff are no longer required.
