Show JINM. An electric machine that lays as many bricks as 20 masons is being marketed in the building trades. Three men operate it. The labor of 17 men is saved, released for other kinds of work. This is typical of the history of applied inventions. Tou picture a future race with nothing to do except run machines, make them, mine and operate ores and grow food. These tasks can be made easier by machinery, but never displaced by it. There'll always al-ways be plenty of w'ork, though a one-hour work day may be the rule a long time after we're all dead and forgotten. s |
