If we design an MCP that exposes all hardware attached to a PC to an AI, can it learn to control them all without drivers and become an operating system by itself?
Discussion
Unfortunately no
More likely it makes better drivers 😂
Sure but then you have added a very large layer of complexity just to turn your operating system into (a very inefficient) prompt box.
It couldn't learn in any meaningful way unless you continuously train the models and prompt it to be aware of its suggested direction.
At the end of the day you aren't getting an LLM to replace the humans that select the data they are trained on.
Look to Machine Learning. The overlap is where AI shines.

Here is some more info in the ballpark of "LLM operating systems" but there is still the major caveats I mentioned above

I built a super small thing. It’s amazing how much better it is when optimized for one task instead of all
Sounds like Karpathy's LLM OS framing: https://medium.com/@marcelheinz/the-llm-os-a-glimpse-into-the-future-of-tech-with-andrej-karpathy-3bcbc0baf339
I think with the current state the context would be way too broad to get any desirable outcome.
