There was a great talk I can't find right now about how the share of computer hardware that it's directly controlled by the OS kernel keeps on shrinking.

In a modern smartphone, the OS directly controls just one of a dozen chips. The rest are running their own OSes which do their own thing independently of the main OS.

I'm guessing it's Tim Roscoe's keynote on how most fundamental questions about what the hardware is actually doing are invisible to traditional OS abstractions:

Roscoe's talk is fairly long (the video is > 1h), but the basic thesis was taken up in a segment of Bryan Cantrill's 20 min OSFF talk:

Both talks are very good; I recommend watching both, in either order.
