I just don't know that I see it running any better for the vast majority of processes that I could imagine running on it. Was literally just transcoding some video, playing a podcast, and browsing the web. Would this be any better?

I think that is largely my qualm with the dream. The only way this really works is if we had never gone with preemptive multitasking, it seems? And that just doesn't seem like a win.

You do have me curious to know if things really do automatically pin to a cpu if it is above a threshold. I know that was talked of some, did we actually start doing that?

Yeah that's the perfect use case for current system design. Nobody sane wants to turn that case into an embedded system running a single process with hard deadline guarantees. Your laptop may not be ideal for controlling a couple of tonnes of steel at high speed, for example. Start thinking about how you would design for that and you'll see the point (whether you want to agree or not).

Apologies, almost missed that you had commented here.

I confess I assumed writing controllers for a couple of tonnes of steel at high speed would not use the same system design as a higher level computer would? In particular, I would not expect most embedded applications to use virtual memory? Is that no longer the case?

"Hard Real Time" is the magic phrase to go as deep as you want to.

This isn't really answering my question. Have they started using virtual memory in hard real time applications? Just generally searching the term confirms that they are still seen as not compatible.

In addition to search engines you can learn a great deal about all sorts of things using an LLM. This works well enough if you don't want to pay. They are very patient and you canb go as deep as you want. https://duckduckgo.com/?q=DuckDuckGo+AI+Chat&ia=chat&duckai=...
