There will always be cults of lonely rejected people that are involved in the columbine styled culture. That includes the Eliot Rogers types as well, whom Roger's mentioned about releasing a bacteria/virus that could kill all other men in the world except himself. The idea wasn't new of course, just that it was made high profile. So if it was really easy, we'd have an army of nerdy autistic incels in the biohacking movement trying to make a utopia where women will chose them due to lack of competition.

But the way us common folk hear things is over simplified. I guess there are machines that can produce any 20 block sequence you want, or you can order them at cost. There is also freeware that maps the human genome. I haven't done the kits or any genetic engineering, but I guess those kits introduces people to some basic hands-on techniques techniques-which I haven't an applied clue about. Supposing one gets that far, everything that sounds cool or possible you just realize is some label. And you don't have a clue about what that label actually translated to.

SHANK3, ok, what is that in code. And how do I identify what are the multiple copies that makes ppl super smart. Or the mutation that typically could mean autism. Or the absence of it that could mean schizophrenia or something else.
CAE (a common tumor antigen), what is that in code.
etc, etc
What is that sequence to get double muscles?
