> All you have to do is perform the most basic of optimizations

I mean, of course this is possible, and every compiler everywhere hopefully optimizes this, but at the same time you need to understand why one is faster than the other in order to understand why it makes sense to optimize it. In the end, you’ll acquire a more in-depth understanding of these semantics.

Regarding the inner workings of a CPU, I wasn’t claiming you will completely understand a CPU, my god I hope you don’t because it’s a crazy rabbit hole.

Again, I was thinking about the higher level, like touching the top of the iceberg and seeing what’s in there. Many a programmer don’t have any idea how function calls work, or how functions return values by using the stack, etc etc.

Bottom line, just because you don’t learn everything, doesn’t mean you’ll learn something.
