"Then take it one step beyond that. Let's say you want, oh I don't know, let's say thermographic vision, but you don't want surgery. Theoretically, we could virally implant a gene complex that alters the cells in your retina to give you thermographic vision. Or how about faster reactions? Perhaps some virally mediated genetic adjustment to the cells of your adrenals. It's one step beyond SPISES, because there's absolutely no implanted hardware."
