I don't think either, people forget that agents are also developing.

Back then, we put all the source code into AI to create things, then we manually put files into context, now it looks for needed files on their own. I think we can do even better by letting AI create a file and API documentation and only read the file when really needed. And select the API and documentation it needs and I bet there is more possible, including skills and MCP on top.

So, not only LLMs are getting better, but also the software using it.
