There is a notable difference between say, calculating long division through a calculator compared to prompting an AI to calculate the derivative of a simple continuous function. one requires _understanding_ of the function, while the other just skips the understanding and returns the required derivative. One is just a means to skip labor intensive and repetitive actions, while the other is meant to skip the entire point of _why_ you are even calculating in the first place. What is the point of dividing two numbers if you don't even understand the reason behind it ?
I'm not quite sure I understand the logic of this and how people don't see that these claims of "well now everyone is going to be dumber because they don't learn" has been a refrain literally every time a major technological / Industrial Revolution happens. Computers? The internet? Calculators?
The skills we needed before are just no longer as relevant. It doesn't mean the world will get dumber, it will adapt to the new tooling and paradigm that we're in. There are always people who don't like the big paradigm change, who are convinced it's the end of the "right" way to do things, but they always age terribly.
I find I learn an incredible amount from using AI + coding agents. It's a _different_ experience, and I would argue a much more efficient one to understand your craft.
