Intelligence is so vaguely defined and has so many dimensions that it is practically impossible to assess. The only approximation we have is the benchmarks we currently use. It is no surprise that model creators optimize their models for the best results in these benchmarks. Benchmarks have helped us drastically improve models, taking them from a mere gimmick to "write my PhD thesis." Currently, there is no other way to determine which model is better or to identify areas that need improvement.

That is to say, focusing on scores is a good thing. If we want our models to improve further, we simply need better benchmarks.
