1. ASSEMBLY and how CPUs and human long and short term memory work, and how which networks in the brain exchange between these blocks (among others, but shhhh)

2. Math, Tensors (you'll get why later) and Matrix Transformations, and all that sin cos tan stuff

3. Ben Eater-ish stuff on YT because it's 2025 and Computer Science is about to (you are ADHD, so anything from 2 days to 7 years) change without anybody noticing ... think AIs having a preference for certain voltage drops and materials ... ... ...

4. the while 37-year-old part is irrelevant because, again, it's 2025, and pretty much any PhD can be caught up with within 10000 hours aka 3-4 years ...

5. you should start a reddit thread where people suggest stuff you SHOULD do instead of CS and thinking in general and some rich guy should hire some people to remind you of all those suggestions multiple times a day
