"Why quantum mechanics might need an overhaul"

I was glad to read this. When I encountered quantum mechanics in college, I thought it was too strange to believe. But then I thought 1) I probably just didn't understand it, 2) so what if Schrodinger's cat and "spooky action at a distance" didn't accord with my intuition; Newton's theory wasn't intuitive to many of his contemporaries and Big Al's stuff was pretty strange, at first, too, and 3) the fact that it just works, all the time and in every instance, was a really good argument in its favor.

But Steven Weinberg, a Nobel laureate and 83 years old, now has some doubts.
