The fact that this is easy enough for a member of a silly cult to
accomplish is very significant. I now suspect that this has been done
before by wealthy would-be parents who kept it quiet. This will surely
change humanity, but it is difficult to imagine how. The more popular
scenarios seem very unlikely to me:

1. The weirdos who want to clone tyrants and cult leaders will be very
   ineffective, and so will be any clones they manage to create. I believe we
   are already surrounded by thousands of would-be Hitlers, Stalins, and Jim
   Joneses, but it requires unusual circumstances for someone to be permitted
   to do so much evil. An evil clone will be preceded by knowledge of his
   propensities and possible agendas, which will greatly reduce the clone’s
   effectiveness.
2. There will be very few if any instances where someone grows clones to
   harvest for body parts, and those who try to do this will be prosecuted
   severely by any government.
3. Given that the vast majority of children are not preceded by any
   planning nor preparation whatsoever, neither cloning nor any other type of
   genetic engineering will become the typical way to have children.

On the other hand:

1. Some people will be able to get some semblance of their dead children
   back.
2. Our future Ghandis, Einsteins, and Mozarts will surely be cloned, though
   it remains to be seen whether people with identical bodies will be similar
   in accomplishment.
3. A small percentage of people will choose to have children with “known
   good” DNA instead of risking a new and untested combination.

Overall, this seems more likely to be a good thing than a bad thing.
