So, basically AI Winter? :-)

That's how I read it XD "oh no, RL is dead too"

I didn't get the reference. Please elaborate.

Karpathy colorfully described RL as "sucking supervision bits through a straw".

he said RL sucks because it narrowly optimizes to solve a certain set of problems in certain sets of conditions.

he compared it to students who win at math competition but cant do anything practical .

Which podcast?
