I am so happy that we are moving in the direction of using stem cell research to help save lives, but I am very afraid that someone will make or is right now making human clones using this same technology. Don't be surprised when this pops up because it will my people. Nadia the octa-mom wanted lots of children. She used modern science (embryos) and got what she wanted.
Some crazy out there wants to have an identical twin and will do just that or at least try.
We will see.
