All of these assume that the conscious "you" knows better about optimizing some meta-objective function than does the limbic "you." Except the latter has been proved out to be species-useful for tens of millions of years, and even more if cross-species evolutionary conservation is considered.

So the interesting question from my PoV is: beyond the immediate reward you hope to enjoy (e.g., loving the pizza as much on day 3 as on the first bite; easy relationships for 500 days) what would the consequences be of these overrides? I'm betting they're all catastrophic, but it's fun to think about the nature of the catastrophe.

One of the things that makes humans dominate the planet so thoroughly is that we are programmable, so we can evolve culturally on a scale of decades, instead of genetically on a scale of centuries.

The side effect of this is that that parts of us that aren't programmable are not keeping up with rapidly changing environment eg being both cognitive misers and obese (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4547044/).

It does lead to a neat heuristic though - if some easy change improves intelligent/memory/whatever, it should be expected to have side effects that would have been a poor tradeoff in our ancestral environment, otherwise it would have been selected for already - https://www.gwern.net/Drug%20heuristics
