more men are daily bound down as slaves to tend them, more men are daily devoting the energies of their whole lives to the development of mechanical life.

Context

“it is true that machinery is even at this present time employed in begetting machinery, in becoming the parent of machines often after its own kind, but the days of flirtation, courtship and matrimony appear to be very remote and indeed can hardly be realised by our feeble and imperfect imagination. Day by day, however, the machines are gaining ground upon us; day by day we are becoming more subservient to them; more men are daily bound down as slaves to tend them, more men are daily devoting the energies of their whole lives to the development of mechanical life. The upshot is simply a question of time, but that the time will come when the machines will hold the real supremacy over the world and its inhabitants is what no person of a truly philosophic mind can for a moment question.” source
