Comment on MIRI's Approach

The concern that ML has no solid theoretical foundations reflects the old computer science worldview, which is all based on finding bit exact solutions to problems within vague asymptotic resource constraints.

It is an error to confuse the "exact / approximate" axis with the "theoretical / empirical" exis. There is plenty of theoretical work in complexity theory on approximate algorithms.

A good ML researcher absolutely needs a good idea of what is going on under the hood - at least at a sufficient level of abstraction.

There is difference between "having an idea" and "solid theoretical foundations". Chemists before quantum mechanics had a lots of ideas. But they didn't have a solid theoretical foundation.

Why not test safety long before the system is superintelligent? - say when it is a population of 100 child like AGIs. As the population grows larger and more intelligent, the safest designs are propagated and made safer.

Because this process is not guaranteed to yield good results. Evolution did the exact same thing to create humans, optimizing for genetic fitness. And humans still went and invented condoms.

So it may actually be easier to drop the traditional computer science approach completely.

When the entire future of mankind is at stake, you don't drop approaches because it may be easier. You try every goddamn approach you have (unless "trying" is dangerous in itself of course).
