Surely nobody is surprised? Perfect knowledge of probabilities, no emotion and immune to bluffing.

It's not immune to bluffing, it's just better at it than humans are. Bluff too much, and your opponent can just call you whenever he has a strong hand, winning more often than not. Don't bluff enough, and your opponent can fold whenever you bet, knowing you probably do have a strong hand.

Find the right balance, and your opponent can't exploit you. With no-limit hold'em this is extremely complicated, and until recently the best humans have always beaten the best bots.

Hmm, why is it surprising that AI is good at poker? The way I see the game is that a bad poker player will just hold a model of his hand in mind. A slightly better one will also hold a model of his opponent's hand. Even better one will also model his opponent's model of himself... and so on recursively. And who's really good at recursion? Computers.

I believe the poster meant a machine-learning system blowing up (catastrophic trading loss) due to a black swan event that the system wasn't trained to deal with.

Knight's blow-up was a process/sysops failure, not due to their strategies going wonky.

[As a side note I believe their core strategies were human-analyst designed, not ML based, but I could be wrong.]

Why's this an argument against AI run hedge funds? Funds run by humans also blow up due to black swan events.

Not quite. This was merely a simple deployment mishap due to repurposing a flag which triggered deprecated code paths that should have been gutted out.

There's no such thing.

An algorithm playing straight hand value based on probabilities is more susceptible to bluffing, not less. And this is no limit, where a single hand can swing all the chips.

Any poker AI that isn't a loser is going to have some pretty sophisticated modeling of the opponent.

Unfortunately this fails to impress me, merely because you could theoretically build a terrible AI and still win.

Just showing your ignorance. That margin of victory over that many hands isn't luck or coincidence. The pros were absolutely dominated.
