So there is a rule which all industrial entrepreneurs either follow or fail to follow which dictates when to build that machine: You build it when you can see you have a repetitive process; and when you have the necessary vision for the machine which establishes how much labor you will save over the need to do the intended work.
That's the balance of usual facts, not new facts, which give the machine the nod. There is no failure to realize this which prevents us from building the machine; the problems which prevent you from building the machine are necessary finances, and/or a monetary system which would deprive the prospective market of the ability to afford the product of the machine, even if you build it.
So then, if you really want to free labor from unnecessary repetitive tasks, and if you really want to free the whole of us of unnecessary labor in producing what we want or need, you eradicate whatever subversions of commercial trade and industrial development preclude this natural objective.
Until Zeitgeist or anyone else proves otherwise, the one effective manifestation of that necessary eradication is mathematically perfected economy™.
