Probably this is the first time ever that professors have agreed on anything, so this is really quite remarkable. We spend most of our time arguing about everything and not agreeing on anything. Having such widespread agreement with over 170—I think the number is now 179—professors signing on to this is extraordinary. It's completely unprecedented. I've never heard of a situation like this before where there's been such widespread consensus that there is a problem.
