It would absolutely be a phase change in practical utility, but it still wouldn't be "super intelligence".

I think that just like there's tons of different kind of "superheroes" and nobody disputes whether they're genuinely deserving of the name or not, there could be many valid types of super intelligence.

If something is roughly as intelligent as a normal human expert in a given area, but 100 times faster, that would be a valid example of super intelligence.

I'm sure that by some definitions like this we've already discovered narrow super intelligence.

For example - breadth of knowledge. Is knowledge a kind of intelligence? If so then current agents absolutely have a breadth of knowledge which is superhuman.
