I agree with you. That said, I can see how AI could be leveraged to generate implementation of highly precise specs. Code would probably evolve to be more about defining desired behavior, very formally, and AI could possibly build the implementation of it. I suspect this would be at the function level first, or unit, like maybe a set of data and a few functions over the data. You could describe clearly the expected behavior, in a formal language, and then AI could write a highly optimized implementation of it.

Now, would this be just as tedious? Would it make coding any faster? Dunno. Maybe the coding of the spec would be almost harder, and a bad spec would still result in bugs in the code.
