Software Is Completely Solved

If each entity creates their own specialised SaaS, to be used privately, that becomes less useful if each corporation (this could also be for a different department within the same business entity) cannot interoperate or integrate with other parties, where they would've produced software for the same purpose. An AI-implemented SaaS is fine, but it cannot run a standards body or autonomously integrate with a different enterprise as it looks today. This is a problem that ought to be solved. OAuth/OIDC paves part of this path I guess.

Maybe personal niche software is solved, but enterprise software isn't.

Also many times solving a problem people don't even realise they have, would still give immense value to the one who creates it, even though anyone could have created that software if only they thought about/identified the problem.

As they say, we will have a renaissance of software development
