It seems reasonable to say that technology generally increases output per unit of labour. Therefore in any factory which has installed new technology one can reasonably expect that for the same output one is likely to need less employees than before (or perhaps the firm will retain the same number of employees but output will increase). Therefore, in either case, the output per employee has increased. Therefore one could say that labour has been saved by the new technology. One could also say that labour has been augmented by the new technology as each worker is supported by the new technology and is now more productive.
My question is: do we have clear definitions of these two terms and what is the difference?
