It isn't just cultbrain, but also a big dose of science fiction and tech hopium. A decade+ ago Lepht Anonym gonzo biohacked themselves to have magnets in their fingers, and this (together with some other science media and science fiction media) set off quite a wave of biohackers. This is just the tail end of the more speculative part of that wave. ('biohacking' (bit nebulous term) can have some good results when people learn how to homebrew hormones or insulin, so don't throw out the meds with the bathwater and mint breath baby)
