I will admit I worry about genetic manipulation technology.  The temptation to "improve" and give the offspring every opportunity, according to the prejudices of the parents, will be huge.  First we will work at eliminating genes that bring about diseases, without considering that nature may have struck a balance here so that removing the gene will have other consequences.  Then we will consider things like height and skin color and of course sexual orientation.  First the blind and deaf communities will disappear, then the gay community.

If most Asians and others too had there way all babies would be boys.  They had better not remove gay orientation is that is the world we are going to create.

What about a world inhabited entirely by geniuses?  I think it might be a nerdy place.
