Unfortunately it doesn't seem like "hal" is available to the general publc. Hmmmmmmm. This naturally gives rise to certain doubts.
There has been a lot of research about chess playing and AI. Can Hal learn how to play chess? Oops, sorry, we don't have any access to Hal.
At the moment, I don't care much how well Hal plays chess, just that he can learn how to play chess. If he can't, it instantly disproves the supposed "AI" bullshit. If it can, it is an impressive accomplishment even if it doesn't entirely fulfill the Turing test..
