Oh for sure, but I think generally multiple experts are selected in an MoE pass for a token, so presumably it'd select programming related ones as well as general knowledge/language.
Only problem would be the routing layer works on the previous token as far as I understand so it might need more informational depth than just "a token" to select experts, I suppose in the same way attention works.
I wish I had the GPUs to run those sorts of experiments ha ha.
