Yeah, that's more or less what I meant. It's not destroyed as in disappears, it's converted into energy, and... goes away, but that's still something.
I also realize we'd get less mass, some of it was blown away due to radiation after all, but the post implies that 100% disappears after decay.
Original post should probably not be taken too seriously, but this is this time when it was so wrong it made me uncomfortable :)
