Technology is a double-edged sword

Mr Lee Teck Chuan said rightly that it is foolish to halt the relentless advance of technology (“Halting advances in technology a fool’s errand”; Oct 20).

The recent advances in robotics, 3D printing and the search for alternative energy sources are mind-boggling. With the advent of cheap drones, farmers can now increase their yields and reduce crop damage. Technology is, however, a double-edged sword.

With robots, the demand for human labour will be reduced, and more people will become jobless. Our children are glued to their smartphones, and human interaction is reduced to a minimum. Blessed with modern technology, are we becoming more introverted?
