First of all you can't brute force the chess. Algorithms that beat high level chess players are non-trivial, even with todays computers. In fact top engines today all use carefully designed heuristics hand-crafted by experts -- this notion that Big Blue, Deep fritz, etc were dumb "brute force search engines" is a misleading tale. Second, in the 70s there was no computer power even for quite clever algorithms (that pr…
You might be right about chess, but I can't understand how you think chat bots are "doing pretty well". I've never seen a conversation with one that held up to even the most tolerant hand-holding for more than a few sentences.
In fact I'm quite sure Turing would be quite impressed by good recent chatbots.

From the point of view of the 1940s, this would seem really close to a veritable "Thinking machine"! Although I'm sure he'd recognize a few things are still missing to fully replicating human behavior (or going beyond).
