Deep Mind's big thing with the game of go, and in general to be honest, is Reinforcement Learning (RL), a branch of ML that until very recently was mostly ignored by industry, and only now gets love because of its perceived utility in some parts of the GenAI tooling chain.
I think even with that in account, RL has only reached a tiny fraction of its potential. We have focused so much on supervised and unsupervised learning for so many years, and then been wow'ed by LLMs we have only see RL start to impact industries in self-driving/flying vehicles, and forget about all the other potential.
The thing about RL that people don't seem to understand is that it is mathematically proven to find the optimal control policy.
In the context of go, that means the only way it can be beaten is through variance (or "luck", if you prefer). As there is no dice or random element in go, the top players in the World basically have to be optimal in every move to get a draw. And then again, and again, and again.
And that's the best they can do if the RL algorithm has stopped learning - it's found an optimal strategy, and it can't be beaten, only matched.
Think about all the optimisation and control problems out there that could benefit from this. And yet still we seem to think it's like supervised/unsupervised learning and only "accurate" to ~90+%, and so it doesn't get the attention it deserves.
Or perhaps I'm a dreamer and an optimist and you're right.
I would happily take the other side of that bet though. At even money, I have all the EV, I'm confident of it.
