CRISPER is a recent technology that allows editing of genes. It allows people to edit their DNA inexpensively and accurately, which makes it possible for the public to do research on gene editing.
I think this technology will mature in the future and make people better, but I'm equally concerned that people's altered DNA will do the same. So I made a process from a toy doll to a pattern, and used it to represent the gradual convergence of human DNA, to give people some warning.
