I definitely think they are a threat to workers in the sense that corporations are going to be replacing workers with AI. It depends on the line of work, of course, but many factory jobs especially are going to be automated. Corporations want to make the most profit, and cutting back on the cost of workers with AI would definitely increase profit for them.
It will be more efficient to have the processes automated, but, in the end, it won't be good for those jobs to be replaced by AI.
