For instance, the first drill presses were hand cranked, which when converted to electricity increased. After a while it was found that by increasing the machines autonomy by stinging them together in an enclosure, can produce exceptionally efficient macro machines called ''factories''. | ||

This stepping up of complex systems is also comparable to the world of computers. The first computers took their energy from manual cranking, which processed instead of physical inputs, processed information into other kinds of information (productive output) via a function with cogs (Figure 2) with the externality being the CO2 in the crankers breath. Computer mechanisms were further refined in being powered by electricity and the cogs being replaced with virtual parts called algorithms. Many different algorithms came together to make the modern operating system which is the equivalent to a virtual factory. | This stepping up of complex systems is also comparable to the world of computers.
