The difficulty of capability progression depends on the distance between successive rungs and the effort required to create those rungs.

“and like also like primary school like English and stuff so it was like a decent language model and they tried to RL it to do like you know late high school and college maths and the gap was just too large like they couldn't get it to climb at all like but if you did like successive rungs of like you know your seventh maths and then your eighth maths and so on like you could obviously climb to year 12 so like again it's just like what is the distance between the rungs on those ladders and how hard is it”

“what is it to create yeah”
