Well, quantum physics seems to be as relevant as Newtonian physics since it
describes what's really going on (as near as we can manage at the moment).
For non-relativistic speed differentials, and macroscopic scales though,
Newton is a good enough approximation to get by with. We don't need to
worry about things closer than that in most situations. So what if the
plane you rode today put your watch a fraction of a microsecond off from
the rest of the world? You almost certainly put more error that that into
it when you set it last. I'm just glad the guys who designed my GPS
receiver understood his math...

a locally deterministic universe?
>From the perspective of things like watches in motion, seeing cars and not
getting run over by them, etc., yes, he's not relevant at all. From the
perspective of the speed of light barrier probably meaning we are all stuck
in this one little solar system forever, he's very relevant.
I'm hoping he turns out to be at least as "wrong" as Newton was...i.e. he's
right under the right conditions, but off at least a bit otherwise. For
instance, perhaps he's only right when you are deep in a gravity well and
maybe things work differently out where space is "flatter". Could
be...almost all the data we have to work with originated in deep gravity
wells...and was collected in one too.
