We will. That has happened repeatedly in the past. It is no more logical for us to worry about humanity in 100 years than it would have been for people in 1900 to worry about us today.
Think of how much has been invented -- yet they would have been concerned about horse poop buildup and poop dust all over everything. 'Let's limit use of horses!" slowing the economy and leaving us with, say, 1980 level tech, "helping" absolutely no one.
So, to people 100 years from now. What did we do? Keep a powerful economy so you can have flying cars and autodocs, or weaken and hobble is so you don't?
We are the people in 1900 looking to hobble ourselves to "help" those way off in the future...of 2014.
Thanks for the "help".
