The article title is a little misleading. He says he wants to see proof that AI is generating actual value by seeing actual economic growth as a result. He doesn’t like the hype, which is based on arbitrary goals that have no tie to actual value. Hence there is not really a disconnect between his statement and his actions as portrayed here.
He never said "That AI Is Generating Basically No Value"
what he actually said: https://youtu.be/4GLSzuYXh6w?t=977
basically that we haven't seen the GDP figures shoot up yet.
He also points out he's not an economist. GDP is not a good very good guide as to whether something has value or not.
