Why do we have php, .net, Django?

Why react, angular, whatever else is front end?

Why different clouds and similar services?

Leader, front runner, early adopter and not invented here mindset allows competition and community to rally around what will become the next big thing

That’s a fair point — ecosystems naturally evolve with competing frameworks, and sometimes that diversity helps the best ideas emerge. But in those examples (PHP vs. .NET vs. Django, React vs. Angular), we usually see clear differences in philosophy, performance, developer experience, or use case fit.

What I find puzzling in the current wave of AI agent libraries is that many seem to be doing almost exactly the same thing — wrapping LLMs, defining tools, planning steps — just with slightly different APIs or names. It’s hard to see a fundamental divergence in capability or vision, at least so far.

So my question is less about why variety exists — and more about whether this current fragmentation is actually productive, or just noise driven by branding and platform lock-in strategies.

Would love to be wrong here if others are seeing more substantial innovation beneath the surface.

roight but not every company is making their own language / framework
