RK,

but when this technology is
extended to airplanes whose occupants don't have the option of pulling
a handle when things go badly then we must be very careful. I'm sure
the problems can be solved, probably with multiple redundancy, but a
century of experience with aviation shows that we must always consider
the possibility of failure.


And your worries show in the accident statistics of the Boeing 777 and
the Airbus 32x and up exactly where, after over 20 years of service?

A single point of failure in an inadequately designed and
tested system could conceivably leave a pilot deaf, dumb, and blind.


There's a ton of single points of failure in any aircraft ever designed.
