Stuff people was scared about when they was invented
Trains,
When the Stockton-Darlington Railway opened in 1825, people feared the worst: the human body, surely, wasn't made to travel at incredible speeds of 30 miles per hour. People genuinely believed that going that quickly would kill you in gruesome ways, such as your body melting.
Telephones,
The telephone wasn't greeted with universal enthusiasm. Some elderly people feared that touching it would give them electric shocks, while men worried that their wives would waste too much time gossiping. In Sweden, preachers said the phone was the instrument of the Devil and phone lines were stolen or sabotaged; others feared that the lines were conduits for evil spirits. The invention of telesales would prove them right.
Television,
We've all been told to sit further away from the TV for fear of ruining our eyes, but it turns out that there's fire behind that smoke: in the late 1960s General Electric shipped faulty television sets that emitted dangerous X-rays and officials warned against sitting too close as a result. GE fixed the problem, but the scare lived on.
