I want to learn how a computer works from a high level. Mostly what a chip is and what it does, but also how it fits into the overall picture.

Can you recommend me a good tutorial/explainer?

Please don’t recommend CS books or courses, I won’t be able to read/follow these. Just looking for digestible high level stuff. Here’s my research goal, btw https://twitter.com/hasufl/status/1266155821840334848?s=21
So knowledge specific to the domain of mining hardware also helps a lot! https://twitter.com/hasufl/status/1266155821840334848

Thank you for all your amazing recommendations! I've just started working through them. Will report which one worked best for me.

Transistors are actually bonkers. Hard to believe that humans invented this!
