They're just language calculators.
I see your point about things not changing much, and while I might agree, I think it's more for the wrong reasons. I think that the math standards that we teach are stuck in a rut where we SAY we want students to be college and career ready yet we don't actually change anything. The skills you need to be college and career ready are a moving target yet our standards are not.
I believe that our standards should more closely reflect the skills people will actually need. If we're no longer doing skill A, that frees up time to do skill B which we always needed but never had time for. So I might agree with you but more because I think that it's too hard to make change.
The greatest effect the calculator had on curricula was precipitating the advent of the personal computer. I feel the same way about chatbots, this is just the first useful iteration of what's to come.
