I was listening to this podcast with Jeremy Alm, who said:
“My main dissertation result was a conditional result. And about four years after I graduated, a Hungarian graduate student proved that my condition, like my additional hypothesis, held in only trivial cases.”

I picked out this episode (“In which every thing happens or it doesn't”) because I thought it was going to be about the ergodic theorem, and I would like to understand the ergodic theorem. But it turned out to be about the Rado graph. That's OK, I'm always up for some hot Rado graph action.
