Adrian Schwinger (at least as much a big dog physics guy as Feynman was) believed Feynman's view of quantum mechanics to be fundamentally flawed. It has to do with reconciling Maxwell's equations with quantum theory.

If Feynman is correct I read that quantum computation is possible, and, if not, is not.

There is a fairly respectable group of physics people who say that the observed behavior of GPS satellites violates Relativity theory. Therefore relativity theory is wrong. These guys are pretty far up there in the physics world as far as I can tell.

Everybody wants to believe that they know what they are doing. I doubt anyone does.

I don't think that's true. GPS positioning uses a leading order correction based on General Relativity to compensate their positioning. Without it the satellites would lose several meters of accuracy every day.

The Schwinger-Tomonaga operator-theoretic approach to quantum electrodynamics was shown to be equivalent to the Feynman sum-over-histories approach by none other than Freeman Dyson (an act which secured Dyson a permanent faculty appointment at the Institute for Advanced Studies).
