I think his statement — ‘Still kinda hard to believe this was considered *impossible* 5 years ago’ — is vague enough to border on being meaningless. He doesn’t say by whom and even when you say ‘generally’ it’s unstated who you mean. I gather you mean by experts in the field and not, say, the general public or even educated members of the general public. 

By the way, I was thinking of how back before SpaceX accomplished this I thought it was very high risk. Not impossible, but definitely not the route I’d advise taking. Am I wee too cautious or was SpaceX just lucky? (Or is that SpaceX is different enough in its aggressive product development process that my opinion (non-expert, of course) might apply to your ‘average’ rocket company but not SpaceX?)

Regards,

Dan
