Through a sufficiently narrow lens, any technological advancement can be perceived as a threat. If your job was to perform calculations for your company using a microscope and calculator (computer, the job title) then the invention of the computer (the machine) was absolutely a threat to your job security. That's not to say that there aren't challenges to adapting or considerations for how to do it well, but it has always been the case that the old way is a casualty of the new way.
I am neither anti-AI nor an AI evangelist but I think a more productive viewpoint is to think about how these advancements could open the door to new opportunity. For example, democratization of learning. It has never been easier for anyone in the world with an Internet connection and a computing device to have access to a personal math tutor or nutrition coach.
