Unix philosophy is "Make each program do one thing well", but they've made them once, many decades ago and haven't change them much since. The problem here IMHO is the speed at which it all evolves, and even more the speed at which the old tools become obsolete. You start a new project with the current 'cutting-edge' stack, and within the 6 months everyone switched to something else. It's become a full-time job just to stay up to date with everything that's going on, and that means making architecture decisions is a lot harder. Also, I personally dislike the fact that it forces one to pick a niche. For decades you could say "I'm good in front-end dev" and really mean it, and now it's not possible anymore to be truly proficient in all that's going on, you just have to specialize.
