I think we just mean different things by “human level”—I wouldn’t consider “human level” thought running at 1/5th the speed of a human or slower to actually be “human level”. You wouldn’t really be able to have a conversation with such a thing.
And as Gurkenglas points out, the human brain is massively parallel—more cores instead of faster cores is actually desirable for this problem.
