From a naive sceptic ....
"Our algorithms for reinforcement learning"
Isn't that the same as saying "our programming for reinforcement learning"?
On the matter of 10^170 can someone quote a more realistic figure, as from what little of the game i know, the vast majority, 90%+ of possible opening moves are never used, even by absolute beginners.
That must reduce the number quoted by a large margin, maybe enough for the atoms in the universe to take the lead again.
