How would you rate "the control of artificial limbs by thought alone"?

I would rate it scary but intriguing. I wouldn't want an invasive surgery into my brain, but I have use of my body and limbs. Those who do not might find the procedure well worth what they gain, mobility. I think that as they increase their knowledge of brains and bodies that the options will become more appealing. It is a noble pursuit to want to give people back the use of their bodies.
