"What gives people pause is, quantum mechanics is quantitatively precise
and yet it comes with all this conceptual baggage," said David Kaiser,
co-author of the study and professor of physics at MIT."
Well, I guess the problem isn't so much the baggage quantum mechanics
comes with, but the baggage our "common sense" comes with.
Anyway, there's a reason Schroedinger chose a cat for his thought
experiment. They're the only animals in the whole wide world that are
indeed /constantly/ in a superposition of different states. (They also
have that natural instinct for how they should be perfectly able to be
on both sides of the front door at once.)

Indeed, that is also the reason that Schroedinger's reasoning was
faulty. As soon as he closed the lid on the box, the cat was in the
kitchen eating the Sea Bream that Schroedinger was planning to have for
his dinner.

Erwin enters room carrying box. Cat senses radioactive isotope and
flask of poison.
Erwin looks at cat.
Cat disappears.
Erwin changes experiment to a 'thought experiment'.

I like that one. :)
For The Cat a quantum is a unit of luck.

Probably why the Ancient Egyptians who worshipped cats measured things
in 'qubits'.
