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.

- chalst 4y agoI'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: https://www.youtube.com/watch?v=36myc8wQhLo https://www.youtube.com/watch?v=36myc8wQhLo 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: https://www.youtube.com/watch?v=XbBzSSvT_P0 https://www.youtube.com/watch?v=XbBzSSvT_P0 Both talks are very good; I recommend watching both, in either order.
