alt Hacker NewsWhen 99% of React apps (websites tbh, with very few needs for complex reactivity...) including those built by multi billion/trillion $ companies, struggle to produce non-bloated, non-slow, accessible websites, you know that the library is simply too complex to tame.
Of course React can be performant, but still, you're getting a PhD in its internals and hooks to get what you have in vue/nuxt/svelte whatever out of the box.
It does not matter what framework you chose, if you carelessly throw money at something it is not guaranteed to be good or fast. A framework doesn't replace company culture.
Plus, in my experience, PhDs do not make good developers - they often fall into the trap of thinking too abstract vs. being pragmatic.
