During my eighty-seven years I have witnessed a whole succession of technological revolutions. But none of them has done away with the need for character in the individual or the ability to think.

Baruch contrasts rapid technological change with the enduring requirements of human judgment and moral fiber. Having lived through the rise of electrification, mass production, modern finance, and two world wars, he frames “technological revolutions” as recurring waves that reshape tools and institutions but not the basic demands placed on individuals. The quote argues that progress in machinery or systems cannot substitute for personal integrity (“character”) or disciplined reasoning (“the ability to think”). Implicitly, it warns against technological determinism and complacency: new inventions may amplify human capacity, but they also amplify human error unless guided by ethical restraint and clear thought.
