Viral nostalgebraist footnote: eval hill-climbing is an adversarial attack on noticing model gaps

JacquesThibs endorses nostalgebraist's essay, highlighting its footnote: anything formalizable as an eval can be hill-climbed, so we are effectively experiencing an adversarial attack on our ability to notice and name gaps in model capabilities. What's easily described gets optimized away; the remaining gap is what we can feel but not easily describe. Seeing clearly requires a commitment to "moving one's goalposts" and refusing to equate improving metrics with no problem—being right matters more than feeling scientific.
