Well, he says

>To me, it is absolutely wild that you have people — within the bubble and outside the bubble — talking about the same tired, old hot-button political issues, when we are near the end of the exponential.

My interpretation is "It's pointless to discuss the old political issues, because they're not going to be relevant once AGI is achieved". So if he does believe in a plateau, it either contradicts his other prediction (that AGI will be reached in a year or two), or he believes it will plateau after AGI is already reached, which means it's kind of a pointless statement. The important thing w.r.t. all our problems being solved would the advent of AGI, not the plateau.
