The news is cool, don't get me wrong
But I really don't get the idea were we were somehow naive, or why we should eat "humble pie". I dunno what horrible college this guy went to, but mine clearly pointed out that there was a Kuiper belt, and there was an Oort cloud. That there were lots of frozen volatiles out there that our instruments were not yet able to see.
Heck, my 7th grade science teacher pointed out that new comets must be coming from somewhere. That was in, um, '65?
