Isn't software already becoming a part of our biology? wouldn't surgical implants that collect data or pacemakers kind of fall into this category? I mean, I know those require hardware, but it's still running software from within, and for the benefit of, the host body.

Or do you mean you think maybe someday we'll be able to use waves and frequencies to remote influence cellular activity with intent and have what amounts to Bluetooth access to our own physical body?
