Dual use

A NYT piece says "a professor of engineering and neuroscience at Brown University is studying how human brain signals could combine with modern electronics to help paralyzed people gain greater control over their environments." Obviously, the same technology could be used to help perfectly healthy young guys fly fighter jets and helicopters, guide missiles to their targets, etc., all without a "joystick." The Pentagon, of course, is working on this. I am wondering if it is also part of the engineer/neuroscientist's business plan.
