I feel the same way about much of Computer Science. So much nonsense was forced into my head as the "best practices", from OO development to Agile to cloud snake oil to crypto scams. And then on top of that it turns out the CPUs are designed to be inherently insecure so all those amazing mathematical proofs in perfect penmanship were a waste of time.
I feel like OOP, Agile, "cloud" as a concept, and cryptocurrency/blockchains are not computer science topics. The way in which blockchains are implemented, sure, that's math, applied as cryptography, applied to achieve distributed consensus, which is very much computer science. But you specifically mention crypto scams, which is much more applying the general concept of distributed consensus to different areas, and I…
I don't think I've ever heard of a class in crypto scams or Agile.
