Its a bit annoying that ChatGPT (Ai) always repeats the phrase of the question, a human would normally not do that. This makes the answer a bit long and cumbersum. Also Ai tends to apologyze in the first place, if you express something went wrong or just expected another anwer. I also found that you can get different answers on the same open question, which must not be bad but is astonishing. So i asked: 'what is the most important thing in life, please a short answer?'  1. answer was 'happiness' - great :-)

Next time the answer to the same question was 'purpose' - sounds o.k. - but different.

I asked why he changed his mind, and he apologized....
