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.

Failure's inevitable. It happens all the time in a complex economy. And how did the economy produce all these amazing things that we have around us, computers and cell phones and so on? Well, the process was trial and error. There were a bunch of ideas, and the good ones grew and prospered, and the bad ones were pretty ruthlessly weeded out.
