@SamoBurja @MarkLutter @tylercowen 1/ Sorry I'm late guys :D - I'll comment here as a factory owner, buyer of many machine tools, and industrial history buff. First, it's true that today only a few countries make all the machine tools today, so let's look at that history. Thanks for indulging me :-)
@SamoBurja @MarkLutter @tylercowen 2/ Precision machine tools in their modern form were invented in Britain / France in the early industrial revolution to start down the path of standardized / interchangeable parts (which proved very elusive).
@SamoBurja @MarkLutter @tylercowen 3/ They started by making a lathe to make precision screws by hand-making a low precision control screw to cut a better control screw - bootstrapping precision: en.wikipedia.org/wiki/Screw-cut…
