You're talking about undergoing major surgery so you can switch off a light without using the switch. This is a computer forum so it may be an idea you're more used to and will have an unusually high number of people who find such technology legitimate, but the majority of people will find this idea frankly insane. My computer sits here and it works for me, I use it when I want it, I have no wish to have it a physical part of me.
My goodness, I typed this post with fingers, how utterly barbaric!
it's not really major surgery.
people undergo far more major surgery just to have bigger boobs.
