The redirection he called an abstraction, and how it makes things easier to make, with less performance and in manh way it’s good, but there’s a point where it isn’t, and solutions like the idea of needing an AI to tell us everything shouldn’t be required.
I like how he talked about using bare metal to run games and not needing an OS, relying on an ISA, or how games were easier to at one point before excessive abstractions.
One very memorable comment he made was when he was asked about what he thought about the M1 chip running software faster, his response was that we could use current hardware and make it run 100x faster if it was well written. Huge part of the many reason I switched to Linux. ;)
Sounds like the 2 hard things in Computer Science returning! Cache invalidation, naming things, and off-by-one errors. [1]
* "Knowledge is ephemeral": Cache invalidation
* "tower of abstraction": naming things, indirection [2]
Recommendations:
* "Reduce complexity, reduce dependencies": minimise entropy, maximise connectedness
* Learn: welcome newcomers; recurse to the next generation

[2] All problems in computer science can be solved by another level of indirection" "...except for the problem of too many layers of indirection."
