Same here. I’ve come to the conclusion that, if I was unwilling to accept anyone that wasn’t of the calibre of Carl Sagan to fill his shoes, I was probably going to wait a long time. I think Degrasse Tyson’s advocacy for black scientists is admirable, as is his willingness to promote religious reconciliation. These weren’t areas of focus for Sagan, but that’s ok. They can be different people, even imperfect people, and maybe that’s good.
