Earlier quoted context omitted.
A superintelligence is one that exceeds human intelligence in all areas. Which roughly translates to learning, adapting, and performing more quickly and efficiently than even the best humans. This is closely related to "the singularity", which is when technological growth becomes uncontrollable by humanity.
That sounds like a definition designed for goal shifting. This AI is better than human at 99.9% of things, but humans are better at pooping. Therefore we don't yet have a superintelligence.
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.
