Point being that, for the example he gives, it’s also necessary to know how optimized the machine is for performing the computation you want to look up.
I’m having a difficult time adapting to this new reality. Memoization has been faster for most of my career, and if used carefully also improves reading comprehension.
Having to go back to inlining calculations is going to hurt my soul in tiny ways.
