On: Why does deep and cheap learning work so well?

[contravariant]

Well, technically general relativity has no real problems with either of those (there shouldn't be, given that general relativity is the main justification for both). It's the quantum mechanics behind them that's not really well understood.

I've never heard of it being understood at all.

[blueprint → contravariant]

They're posited as a fudge factor -because- the quantum mechanics is not understood.
