DATA FOR MODELLING
“THE SECOND MACHINE AGE”
“Now comes the second machine age. Computers and other digital advances are doing for mental power – the ability to use our brains to understand and shape our environments – what the steam engine and its descendants did for muscle power” From “The Second Machine Age – Work, Progress and Prosperity in a time of Brilliant Technologies” Erik Brynjolfsson & Andrew McAfee; W.W.Norton & Co, 2014.
