Who says it has to be Dwemer?
There are three options:
1. Dwemer = Superior technology so no use
2. Nords = Hate elves, hate magic, wouldn't use it if it was made of gold. Also their primary contact was a war, so they were more intent on killing then on learning
3. Falmer = This is possible, however Falmer society has been wiped otu first by the Nords and then by the Dwemer and what is left is what you see in game today.
