Tyson is not a scientist, he is a shameless opportunist.
As most people are.
Neil deGrasse Tyson
Local city host “forums” which have speakers to do talks , (usually to coincide with a book tour ).
I had worked these events numerous times over the years , most speakers do about 45 mins to an hour , sometimes a little longer, nobody ever exceeded 2 hrs.
This clown shows up and did 4 hours. He was probably hoping some soccer moms would over indulge in wine coolers. Little did he know the bar is only open for the first hour.
Four hours of bloviating . Insufferable..
