Does the world need the "uniqueness" of 40 similar web frameworks?
Perhaps not if the one framework we ended up with was a good one …
As long as there are standards, yes, why not. In Italian we have a saying: il mondo è bello perché è vario. The world is beautiful because it’s varied.
Since a good LLM can handle any of those 40 web frameworks, I think having 40 web frameworks is becoming less of a problem than it used to be. Actually, implementing ideas in an individual manner will become easier. Remember the Bazaar and the Cathedral? The Bazaar kind of failed on the client side, but LLMs may revive it.
the world certainly needs novel ideas. maybe eventually we'll come up with a web framework that doesn't suck - or rather we'll realise that Django had it right all along for all these years.
