The Altmer and certainly the Psijics are already on par with them, maybe the Dunmer too, but expressed via different ways.
You have to understand that TES takes place in an inherently magical universe where our version of science doesn't really work as you'd expect. Every serious scientist would be a magician.
Even Dwemer tech is not so much technology as it is technomancy, using engineering principles to harness what is inherently a magical phenomenon.
The cultures of other advanced races simply do not express themselves in this way. For certain technologies a certain mindset is as paramount as a working knowledge of the guiding principle. The ancient Greeks had steam engines, but to them they were just toys.
Similarly the knowledge held by the advanced races was only expressed technomantically because of the specific Dwemer culture, other races may know the same principles but use them in entirely different fashions, or not at all.
