The speaker says the bitter lesson primarily concerns scaling and compute, but uses it as an approximate analogy for how harnesses quickly become outdated and change in unintuitive ways.

“yeah i mean i think that this is i think the bitter lesson is unintuitive you know i mean in terms of like i also like we're kind of misusing a little bit of the bitter lesson here where it's like it's more about like scaling and compute and stuff but like i think there is something where just like i think i use it as an approximation here to say that harnesses go out of date very quickly you know what i mean and like how but how they change is unintuitive you know and so like”
