If that AI were given an identical human body (and interface to that body) to someone who had not yet learned how to do that, and it outperformed them in figuring it out, then that would settle it.

Otherwise I don't see the comparison.

If I'm intelligent enough to use a tool, but I don't have the tool, that doesn't mean anyone who does have the tool is automatically more intelligent than me.

Likewise, comparing my performance without the tool against someone's performance with the tool wouldn't be benchmarking their performance, only benchmarking them with the tool's performance. The fairer comparison would be against me also with the tool.
