CPUs are so sophisticated now that when you do things like "precompute a lookup table" or "use a clever domain-specific data structure", they just find it patronizing. it doesn't impress them. any attempt to be smart with the instructions you provide? they just roll their eyes. if you tell them to go chase a pointer they're passive-aggressively muttering "great, another linked list" as they performatively brush all the stuff they were working on straight off their desk and onto the floor
