Some things are easier said than done, fighting the source of our problems is one of them (at least for me, shyness is a curse), band aid solutions can make us temporary feel better. Edit: I forgot to say I agree with you, it is not the end goal of AI. I just wanted to share my personal reasons for trying to have more accurate AI.
From what I have seen I still couldn't find anything that can be called "Artificial Intelligence", it feels like we are still in a very rough draft version of what we can call artificial intelligence. I haven't seen much progress in AI in the latest years, algorithms seem to be the same (or variations of them), the difference is that computers got faster and have more memory, this allowed impressive things such as brute forcing chess moves to beat the best player but I wouldn't call it "intelligent". Edit: a disclaimer, I haven't read very much about the machine that plays Go, as far as I know it can't use brute force to play the game but I don't know which algorithm it uses.
