If we create something that can do critical reasoning, all the more power to us.
It seems to me you're not defining "critical reasoning", and that it's effectively a synonym for "intelligence", at least as applied to AI capabilities.
I think AI responses are like the responses of a person who's very new to a subject and doesn't understand it, but they know all of the terminology and how the terms are usually used together. They can be helpful, and often correct, but only an expert in the field is going to know for sure if they're correct. And my fear about AI is not the AI itself, it's how the non-experts are going to use the AI to try to replace the experts in fields where being correct is really important. That will work, but only sometimes. If we don't make the people who choose the AI this way responsible for the outcomes, we're going to have a real mess on our hands.
