I rather wonder what our descendants will marvel at that we are doing.
Will they think that it was ingenious to design machines in different parts, from different materials, then assembled and shipped to where they are needed? With the limited technology and methods of our time? That we used to engineer and create special machines for these different purposes because in their world, everything you can conceive will come out of replicators [0] instead? Fully functional, no matter which materials it consists of? And humans no longer involved in the design process because a solution was computer generated after stating the purpose of the tool?
