People said the same thing about the internet, that you should be getting your information from actual books and that the internet will make you lazy and complacent. There was a time when you were encouraged to write code on paper first instead of typing it directly because it made you think clearly. Some time before calculators apparently dulled your mental faculties, so you should be hand rolling all your calculations. Go back in time far enough and you'll find Socrates disparaging writing because it weakens your memory and destroys your mind. And yet humanity is here and seems to be doing all right. Every generation has managed to produce smart people that have been able to push the boundaries of scientific and technological progress. If anything we may be getting smarter. What history has repeatedly shown is that when you reduce friction for the human brain, it goes and finds more complex things to do. Such a periodic removal of friction, may very much be a necessity for progress, because it allows the paradigm of thought to shift to a higher level. The same should happen with AI as well.
