because the way he is presenting shows lack of preparation. he forgets his words and he has long breaks. he goes over the time so the person responsible is on stage (you can see her near the end of the video) to ask him to wrap it up. which is a shame because what he is saying is indeed very interesting :/
I love the museums he mentioned and many others. Would love to be able to travel more often and enjoy the socializing opportunities he mentions. Museums are timeless treasures.
