It is difficult for me to believe that quantum mechanics, working very well for currently practical set-ups, will nevertheless fail badly with improvements in counter efficiency.

quantum mechanics

decrees key to reality
reality is state of mind
quantum mechanics

quantum physics
decrees 'ultimate reality'
exists but is not
embedded in space time
therefore in what

beyond this life pod
illusion when we shed
body matter restraint
step outside space time
into limitless eternity
does God there us await?

Now, what that means is that there is fundamental indeterminacy from quantum mechanics, but besides that there are other sources of effective indeterminacy.

Quantum mechanics is certainly imposing. But an inner voice tells me that it is not yet the real thing. The theory says a lot, but does not really bring us closer to the secret of the 'Old One.' I, at any rate, am convinced that He is not playing at dice.

The scientists often have more unfettered imaginations than current philosophers do. Relativity theory came as a complete surprise to philosophers, and so did quantum mechanics, and so did other things.

Schrödinger's dog (being an after birthday poem for Miss Ruthie)
Unlike
Schrödinger's cat
Schrödinger's dog
was always
there
under his feet
hungry for
...his Master's voice...a pat...the sound of his step...
The cat
(like anybody's cat)
couldn't give
a toss
(but that was neither
here nor there) .
It's hard to tell
if it's alive or if
it ain't.
It 's one
lazzzzzzy cat.
He's never there
(when you want him to be)
and always there
(when you don't want him to be.)
Quark the cat
was just one big paradox.
The dog
was old and faithful
always
in the box
asleep or gnawing
a bone in thought.
The cat couldn't care
less
a source
of constant
anxiety
about its
whereabouts
and the state
of its health.
Being
neither
here nor
there
or somewhere
else entirely
as if it lived
in a parallel universe.
Lived in a world
of its own.
Thus the theory of
Schrödinger's Cat
proved
(beyond doubt)
that although
cats are nice an' all dat
dogs
are a scientist's
best friend.

In 1935, Schrödinger published an essay describing the conceptual problems in quantum mechanics. A brief paragraph in this essay described the cat paradox:
One can even set up quite ridiculous cases. A cat is penned up in a steel chamber, along with the following diabolical device (which must be secured against direct interference by the cat) : in a Geiger counter there is a tiny bit of radioactive substance, so small that perhaps in the course of one hour one of the atoms decays, but also, with equal probability, perhaps none; if it happens, the counter tube discharges and through a relay releases a hammer which shatters a small flask of hydrocyanic acid. If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has decayed. The first atomic decay would have poisoned it. The Psi function for the entire system would express this by having in it the living and the dead cat (pardon the expression) mixed or smeared out in equal parts.[

There was a leak in my cistern in the brain stem. I didn't like to play dice with my universe so I called a quantum mechanic in. I asked him if it was bad. He said: Well, it is or it isn't...depending on how you look at it.. It's good for me...bad for you! '
'Now, about that cat? '
'Not that old chestnut....the cat is over 70 now...just fix the cistern will ya! I had the cat poisoned...so that's that! '
'Ohhhhh! '
'Anyway...it was a hypothetical cat! '
'Ya mean it wasn't real? '
'Oh...what is real?
He seemed considerably saddened by this and left without charging for the cistern.
I hate when after all this time Animal Rights activists disguise themselves plumbers in order to rescue the bloody cat that is neither alive or dead.
Next time it leaks...I'll call a vet.
