I don't feel it's obvious at all that this will become forced. What would that even mean – you don't get to edit code anymore but can only interact via chat with an AI which edits the code for you? I think it's obvious that's not going to happen.
Will there be a day when you can't turn off AI suggestions for something? Maybe, but suggestions aren't requirements, no one is forced to use them so at worst they're a minor UI annoyance.
I'm interested to hear why you have such a negative take on it? I don't particularly enjoy most AI implementations in products (not Google specific), but they're almost entirely optional everywhere, and ignoring them really isn't much of a problem.
