I would not say "replacing" but rather "helping". Replacing means there is a fixed lump of work, but in reality work scales up when capability improves. When you make the road wider, more cars fill it up to the max again. To think that work is fixed means to believe we can't possibly want more, better and faster. It's not like we are out of ideas. Take software for example - with each new language, library or project on Github we can automate and make it easier to build things, yet after 60 years of self-cannibalizing software we have more developers than ever.
