Tesla was a smart man. My favorite quote of his is:

"The year 2100 will see eugenics universally established. In past ages, the law governing the survival of the fittest roughly weeded out the less desirable strains. Then man's new sense of pity began to interfere with the ruthless workings of nature. As a result, we continue to keep alive and to breed the unfit."

I wish that I would be alive to see if it is true - but that is highly unlikely.
