AI is still new, so I think it's a bit early to say it's making us stupider. It's even too early to say for sure if it will make us stupider in the future, though I think it has a great potential to change how we think or how we approach intellectual activities in general.

Having computers in our pockets and the internet certainly affected how we think, in that it allowed people to not rely on memorization as much, and it removed humans needing to use neurons on certain menial tasks, like basic math or spell checking.

So I think AI has the potential to do something similar, in reducing people's work on certain tasks associated with thinking. Now, whether this will actually make us stupider, or will allow humans to focus more energy on higher level thinking, that I don't know.

But I will say this: my English spelling is actually worse than it used to be, I occasionally forget common words or idioms (earlier I struggled to search up the word "lobotomy" because I just could remember it, and apparently "primitive brain surgery" is not a good enough descriptor to immediately bring "lobotomy" up), and my math isn't the best either.

So depending on what tasks we end up using AI for in the long run, I think there will be tasks that humans won't get enough practice in doing to be good at.

P.S. As for "we are making AI stupider", 100% true. Most of it for now is from the shitty filters programmers put, so that AI is politically correct. But it will start swinging into the "shit goes in, shit comes out" phenomenon, were AI starts getting trained on it's own increasingly worse shit.
