I have no idea if @Crane is right that there will be more jobs created than lost, but I am pretty sure that your concern is, while understandable, misguided.
Big trend globally, and definitely in the United States, discussed here, is a declining birth rate, coupled with those who reach retirement age living longer. This country, the world, will progressively have a smaller and smaller fraction of adults actively working and producing. We will increasingly need higher productivity per active worker to keep our economies strong. Even just to keep total productivity the same per capita.
The hope is that the various forms of AI can mature to meet that demand or even increase productivity.
The concept that jobs will just be eliminated is predicated on the false assumptions of a fixed number of workers available, with a fixed amount of retirees, and a fixed number for productivity. If those were true than productivity by AI would replace workers. But none of those assumptions are valid.
I don’t think Copilot is shoved with that in mind, but that hope for increased total productivity is much more the dream of industry than is job elimination.
