As feedback, this comment took forever to get to the point. It would really benefit readers if you just started with: ‘Contrarian point of view - we don’t need these devices in society because we have an abundance of human labour for that and there are far bigger problems in society to be solved.’ It’s best to get your conclusion out there early rather than relying on the reader to find it. You don’t really provide much of an argument for not using or developing a device like this other than there’s an abundance of human labour. What about if this device became much cheaper than human labour? To your other point about other problems to be solved, if we only ever worked on the problems pivotal to humankind (e.g. global warming) then a lot of things that are useful but not pivotal to human existence would never have been invented.
