Which means that instead of millions forced to learn and get good as part of their job, it would be a much smaller percentage of "hobbyists who love to tinker" doing it.
And even that tinkerer subset would be smaller than before in the future, since now many that would have turned into tinkerers would be tempted to just use AI, or never develop the taste and skills to be good tinkerers to begin with.
So what you wrote proves what the parent wrote, and is not an argument against it. You're basically saying "huge problem isn't a problem because there will always be some small number of people it won't affect".
