Forget the babies, I'm selfish. Can my existing DNA be modified to make me a super-human? How long does it take to replace all the old DNA and cells? Where do I sign up?

With today's knowledge of genetics it ain't happening. We have barely started gene editing for single point mutation diseases like sickle cell. The stuff described in this blog post (which is mostly gobbledygook by the way) are traits that are (1) hugely polygenic and (2) not known well enough from a genetic perspective anyways. It will be decades at best before they'd attempt genetic editing in that scale on a healthy person.

But if we want to solve the second one I welcome it as a person who works in genetics research, always good to have more money.

Replacement time varies by tissue — IIRC skin is ~weeks, brain is never.
