"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.)
