alt Hacker NewsRight, but that was kind of my question? What is better about not having a lot of these things?
That is, phrasing it as a dream makes it sound like you imagine it would be better somehow. What would be better?

Things would be simpler, more predictable and tractable.
For example, real-time guarantees (hard time constraints on how long a particular type of event will take to process) would be easier to provide.

Think about using a modern x86-64 cpu core to run one process with no operating system. Know exactly what is in cache memory. Know exactly what deadlines you can meet and guarantee that.
It's quite a different thing to running a general purpose OS to multiplex each core with multiple processes and a hardware walked page table, TLB etc.
Obviously you know what you prefer for your laptop.
As we get more and more cores perhaps the system designs that have evolved may head back toward that simplicity somewhat? Anything above %x cpu usage gets its own isolated, un-interrupted core(s)? Uses low cost IPC? Hard to speculate with any real confidence.
