Human-level AI will radically change everything, and superhuman AI would probably come right after, so he’s using his own definition of “change” here.

A virtual human that doesn’t need a salary? Doesn’t need breaks? Can work 24/7 at superhuman speed? Can multitask with ruthless efficiency?

That…would change the world much less than we think?

Intelligence as a bottleneck will be eliminated overnight, simultaneously, in all domains.

But sure, some things that we don’t like such as conflict and greed will still be around, and hence things will change less than expected if that’s what you’re hoping will vanish.
