I dislike the manufactured overcomplexity of web app development nowadays, especially in corporate environments. Maybe I'm just curmudgeonly, but all of that command-line building crap with frameworks and dependencies and auto-reloading browsers--I feel it adds a lot of work for little reward, and introduces a lot more opportunities for problems to arise. All I need is a good text editor and a browser with dev tools, thank you very much. Grumblescoff.
