Using Edison as an example, he marketed recording devices and electric lights. Both great things, Edison thought, for mankind. But recording devices led to the resignation of a President and leads to who knows how many breakups of marriages every day. Electric lights have nearly destroyed the night sky and we are supposed to be watching the lights in the sky for signs and seasons, and they also cause people to stay up all night and not get enough sleep.
Whether it is for purely selfish reasons or for altruistic purposes, doing wonderful things might not be so wonderful after all, although the odds are better if things are done for purely selfish reasons.
Tsk, tsk!!!
I expected better.
