Wikipedia says that autism is caused by DNA errors, so the only perfect cure would be, as with many other incurable diseases, DNA editing? I wonder if we come into the future where parents will be able to buy DNA fragments for example, for certain eye color or size, or for thin hands and legs, and collect future child's DNA from pieces. Or DNA will be considered non-copyrighted and owner of elf ears won't be able to sell his unique feature? Seems not fair to me. Also whether there will be pirate sites with DNA.
