I think you're right that it is fear. But it's kind of a self fulfilling fear. Teams are requiring employees to use AI, probably because of this fear. Maybe it isn't directly taking my job, but it is necessary for me to use Ai to keep my job.
FWIW I do client work on the side. Full time client work has always been more draining than just having a regular job IME. Maybe I just can't find the right clients, but that's not something I have to worry about when I work for a company.
Client work is hard, but you have to decide if the freedom to work the way you want is worth it.
But I know not everyone is in my shoes which is where my comment is coming from.
