alt Hacker NewsWhat I mean by the term is creating value directly and in response to immediate needs. E.g. "your sink is broken > your sink is fixed" or "here is your burrito" or, ya know, taking care of kids and the elderly. It's stuff that needs no R&D, but also still has to be done for society to work.
Of course, then these persons should avoid using electric drills, bldc motors, digital verniers etc as these tools required computers and motors that were created out of mathematical and engineering curiosity such as developing the electromagnetic theory not out of value for society to work. Since somehow the act of using this machine is more "honest" than creating this amazing machine in the first place.
