My prediction is that GPS will become a standard equipment in the
cockpit, and will replace the magnetic compass. Sure, the GPS can
fail, but those are technical issues which will eventually be solved,
and the GPS will become more reliable than a magnetic compass. My
guess is that it will be 10 years or more before it happens.

To paraphrase this idea; your prediction is that a GPS, which has
thousands of components with complex relationships and therefore countless
failure modes will become more reliable than a magnetic compass which has
only one failure mode -- the loss of fluid.

I doubt it seriously.
