I don't think it will be regulated well enough, if at all, and besides that, it will result in so many workers being replaced, that we will need a UBI to financially support the surplus workers in our economy, as well as replace their tax revenue, so I see a very dystopian, chaotic future with mass unemployment, starvation, and violence, along with totalitarian crackdown by the fed govt., to deal with the results of it all. Think something like Soylent Green.
