I agree! It has been a great help in those cases.
I just don’t believe that it can fullfill the actual need for sites like StackOverflow. It probably never will be able to either, unless we manage to make it learn new stuff without reliable sources like SO, while also allowing it to snap up these obscure answers to problems without burying it in tons of broken solutions.
Oh, so you want to make a website where you post personal pictures of youself and post updates of your everyday life, while connecting to your friends? It’ll be really big you say? There’s nothing else on the market lile this? Let’s go!!!
