From some of the reporting it sounds like AI was in a bit of a cold war that accidentally turned hot. OpenAI got it into their head that someone else was going to release a chat bot imminently, so they panicked and raced to release their own, which is why it's GPT3 based, doesn't have up to date info and has all sorts of other problems. OpenAI panicked and rushed something out and now Google is doing the same.
All of these companies know the tech isn't ready, but they couldn't afford to be left behind when someone moved. It's funny, because this happens quite often in tech. Remember when Tesla announced self-driving? Suddenly Intel were doing deals with MobilEye and BMW, GM did Cruise etc. etc. and then 5-10 years later nothing has been delivered? They all jumped the gun and couldn't afford ot be left behind.
