Robots can help axe bad jobs, create more good jobs

Do many hands really make work light?

That is what I asked myself when I visited the Pennsylvania, United States-based West Hershey chocolate plant, the largest factory of the American confectionary maker the Hershey Company one month back.

Inside the plant, large-scale and highly automated machines and conveyors far outnumbered humans. Almost every process along the production line, from chocolate tempering, molding, defect detecting to the final wrapping and packaging, was carried out by machines.
