From Can’t to Can
In the 19th century, a bloke named Dionysus Lardner proclaimed that “rail travel at high speed is not possible because passengers, unable to breathe, would die of asphyxia.” If you talked about bullet trains back then, they’d think you were tripping. (An understandable assumption; back in those days you could pop down to the chemist and to pick up some cocaine or heroin to help get over that pesky cold)
In the 1950s, when a worldwide campaign to eradicate smallpox was proposed, many labelled the idea “impossible” and “a waste of money”. By 1980, the disease had been wiped off the face of the planet; UNICEF has estimated that this has saved approximately 5 million lives annually since.
Not so long ago, it was thought that nothing could exceed the speed of light. Surprise surprise, myth busted.
History is a continuous cycle of “I Can” beating “I Can’t”. The secret is to refuse to accept the limits imposed by others.
