I don't see why wireless braking is impossible. Presumably a system could be contrived that is just as reliable as mechanical (/hydraulic) brakes, i.e. 99.99?%. It could, for example, detect failure (loss of connectivity with lever), warn, and slowly start braking automatically. OTOH if all your hydro fluid leaks out (not likely but not impossible) or your cable snaps there's no official warning system in place or way to recover if you do notice.
Realistically the most common form of total brake failure, I reckon, is when the pads overheat or simply wear out. The most common braking mistake would be over-application of the front brake. The most common cause of diminished performance is a poorly adjusted setup. I feel like smart electronic brakes could help improve all of these problems, although I guess it's possible to have smart electronic brakes that use a long cable as a "button" so what it really comes down to is whether you can make a wifi system more reliable than a metal cable or mineral oil hose.
