Ties in nicely with:
"If you think you understand quantum mechanics, you don't understand quantum mechanics"
This might have been true in the days before anyone had the concept of macroscopic decoherence (popularly known as many-worlds) but quantum physics is pretty normal these days. See the recent series at Overcoming Bias.
[This is not to say that those researchers are unintelligent, just that a certain bias may exist.]

Of course, I have a Ph.D. in semiconductor lasers, so I've been trying to think about such stuff off and on for years... which means I'm a terrible test case for articles like this. ;)
