“So yeah, he's had a really tough ride on this, and I think he has proven to be way ahead of the curve. Far beyond its time to warn of some of these dangers.
"But it shouldn't be that there is now a third generation that needs to increase it even more. And you know, to me it would be an relative disaster if George was sitting here talking to you or your successor, Adam, you know 30 years from now, whatever, in always saying the same thing, because by then we will be too late. "
