AI won't replace jobs in that way. What it will do is make people who use it more productive, which will mean fewer people needed to do the work, which means fewer people doing that job. The speed at which it does this is what will determine the impact on how people are affected by it.
Like OP I find AI to be incredibly useful in my job. I was able to learn Ansible in less than a week by asking it how to do things and trying the result. It saves me time by doing grunt work for me that would otherwise be too fiddly or cumbersome to figure out.
We're not going to wake up one day and have AI lawyers/programmers/writers, with all the humans on the dole. What will happen is people who can effectively utilize AI will have an advantage over those who don't, just like people who can use a computer have an advantage over those who don't.
But we also need worker owned cooperatives and a universal standard of living or it's just going to make technofuedalism worse.
