Of course, there's also an interesting worry that's not connected to jobs here, namely, whether we may end up in a new age of SaaS companies selling automation to small and medium sized businesses as their main business model. Imagine if instead of large companies using tech alone, or people buying these machines alone, the likes of Google/Amazon/Microsoft/whatever started leasing them through an AWS esque service for X amount of dollars a month. We've already got Maker Labs and what not, this could be the future for that.
