Another one of the predictions from Nikola Tesla stated, “It will soon be possible, for instance, for a business man
in New York to dictate instructions and have them appear instantly in London or elsewhere. He will be able to call up from his desk and talk with any telephone subscriber in the world. It will only be necessary to carry an inexpensive instrument not bigger than a watch, which will enable its bearer to hear anywhere on sea or land for distances of thousands of miles” (Tesla NY Times). It sounds like Tesla was describing, what we call in modern times, a cell phone. Therefore, this prediction did come true as I knew exactly what he was talking about and I’m looking at my cell phone right now.
The last prediction is from Isaac Asimov. “Much effort will be put into the designing of vehicles with "Robot-brains" vehicles that can be set for particular destinations and that will then proceed there without interference by the slow reflexes of a human driver” (Asimov “A Visit to the World’s Fair of 2014”). He describes vehicles with the ability to drive themselves as a possibility in 2014. Once again, this prediction was correct. There have been developments in cars that drive themselves since 2008. Although there are none available to the public at the moment, they are definitely a thing and car companies are already planning on releasing these cars by certain dates.
I think people try to predict the future because it gives them some sort of relaxation from all of the uncertainties that occur everyday. If they think this will happen for sure, then it puts their minds at ease.
