I have a grad school professor that owes me $1M dollars on a bet that the Patriot Act would never end. I told him he was painfully naive and not suitable to each graduate school economics with such thinking.
"Never" may be falsified by "at least once", but affirmed only by "never". So I'm afraid only you could have ever been on the hook for the $1M, and may still be!
Your prof made a good bet.
Unless your bet was that "it will be strengthened before it is repealed" and then his position was that "it would be repealed without ever being strengthened." Still possible for neither to happen indefinitely though, leaving the bet pending.
Snarky comment meant in good humor.
