People who are not impressed by the innovations of Musk’s companies generally aren’t involved in those fields. I had a NASA fellow (guidance, navigation, etc, so a relevant field) who literally told me landing on a barge is impossible, just months before they accomplished it. I personally think this will take decades. And the implications of it for humanity if it works are probably greater than anything else Elon is working on.
