But I keep a wary eye on them and their ideas from the periphery - lest I be on the the wrong side if they ever become right and start walking.
You never want to be on the wrong side of a wave - it really sucks.
Just look at genetic engineering: this is what the futurists used to talk about. Now in popular culture genetic engineering has a negative connotation due to Gattaca and eugenics and people talk often about bioethics and socioeconomics in this context. However, even now we can do in vitro fertilization while selecting against fertilized eggs that contain a specific gene (such as for Wilson's or Huntington's disease). The beginnings of genetic engineering are already here but it has snuck up on the public, just like technologies will sneak up from behind the futurists.
