This wasn't the point, the central idea was that you said "we can't create a NN similar to a human brain yet", and my counter argument was that we're close to that (close as in decades). The very central point is that scientists are making huge progress in this regard.
Stupid is not the right word, I'd say they're limited. Many people put those bots to the test but that's not what you do in real life with a person, if you just ask simple questions a bot would be able to answer very accurately.
It really depends on the day or week for me. If I had a tough day or week, internally I am easier on myself and the inner monologue isn't as harsh and I give myself some ground. When my week has been good or I had a really good day, the inner voice is tougher. I am not sure if that makes much sense
