You've never actually seen a "real computer" , nor will you ever do
so . The Turing machine requires an infinite tape . At most , you have
pathetic, finite automata. What about if a "real computer" makes a
floating point error when calculating pi? Does that change pi?
All 'models of computation' are abstract, as 'internal to Mathematics'
as they could be .I build a computer not because I can't think my task
out, but because it helps me execute a 'mechanized part of my
thinking' faster. Historically , computability theory relies and is
intertwined heavily with other mathematics, (beginning with
arithmetic , going recently to the high abstractions of Category
Theory), and could not have developed without the existence of said
mathematics. Was Mathematics before Turing invalid or useless?

"What Turing disregards completely is the fact that mind, in its use,
is not static, but constantly developing" -Godel

"It is perhaps just dawning on five or six minds that physics, too, is
only an interpretation and exegesis of the world (to suit us, if I may
say so!) and not a world-explanation; but insofar as it is based on
belief in the senses, it is regarded as more, and for a long time to
come must be regarded as more - namely, as an explanation. Eyes and
fingers speak in its favor, visual evidence and palpableness do, too:
this strikes an age with fundamentally plebian tastes as fascinating,
persuasive, and convincing - after all, it follows instinctively the
canon of truth of eternally popular sensualism. What is clear, what is
"explained"? Only what can be seen and felt - every problem has to be
pursued to that point. Conversely, the charm of the Platonic way of
thinking, which was a noble way of thinking, consisted precisely in
resistance to obvious sense-evidence - perhaps among men who enjoyed
even stronger and more demanding senses than our contemporaries, but
who knew how to find a higher triumph in remaining masters of their
senses - and this by means of pale, cold, gray concept nets which they
threw over the motley whirl of the senses - the mob of the senses, as
Plato said. In this overcoming of the world and interpreting of the
world in the manner of Plato, there was an enjoyment different from
that which the physicists of today offer us - and also the Darwinists
and anti-teleologists among the workers in physiology, with their
principle of the "smallest possible force" and the greatest possible
stupidity. "Where man cannot find anything to see or to grasp, he has
no further business" - that is certainly an imperative different from
the Platonic one, but it may be the right imperative for a tough,
industrious race of machinists and bridge-builders of the future, who
have nothing but rough work to do." -Friedrich Nietzsche
