Subsurface or False Apex

"A machine is a device for tapping the power of nature...Yet as the machine has tapped larger sources of power, it has come more and more to outdistance its natural use. How is it that the machine in its modern form now seems to us a threat?

The question as it strikes us hinges on the scale of power that the machine can develop. We can put it in the form of alternatives: Is the power within the scale of the work for which the machine was devised, or is it so disproportionate that it can dominate the user and distort the use?...And therefore every machine re-enacts the original dilemna: does it deliver energy in response to the demand of its specific use, or is it a maverick source of energy beyond the limits of constructive use?"  -J. Bronowski, The Ascent of Man
