I know I will offend chess players by saying this but.. I feel like chess is more of a IQ contest, while Go is more Art-ish in how you move and slowly cripple and surround your opponent.
Realistically speaking, there aren't that many moves you can do in chess. Most of them are just blunder that would get you insta-killed by a good player. Contrast that to Go where there are so many good moves. This is why I think the Go AI is more impressive.
Part of me thinks that at some point in the future, we'll have Chess "solved". Not in a "That computer is too good for humans", but more in a mathematical sense where all avenues will have been explored and at any point you mathematically know from a position whether you 100% win. So, the computer will make a move, a second computer will make a move, and then they will agree on a draw. To be able to achieve this, I think it will be some kind of rainbow table for chess (on a much bigger scale obviously), where you can represent one position by a hash and just brute-force all possible solution from the "end-game" to the initial board. So, it's not even about AI, more about bruteforce and hardware. I know it's not possible to do this at the moment but quantum computing would be.
Totally could be the same for Go, but yeah the search space seems much bigger. I feel in chess there are a few good moves on every turn whereas for Go it seems there are so many. But then, it may be because I'm less good at Go and I don't see the "obvious" move, not that I necessarily see it in chess but you know what I mean.
