INFJ>
I've studied him before at some point because I got off on a FLW jag....
I see him as a visionary first: Ni.
I feel him as an INFJ/INTJ and his parents as well...
I see him as more artist and visionary. Plus your vid speaks to his ideals of the importance of spirituality. Though I don't think studying someone after their 40's/50's gives you the best glimpse into their type because they should ideally be utilizing all the functions more proficiently by then.
I remember reading that he designed something once and many engineers told him it wasn't strong enough, but he stubbornly followed through on his plan anyway and it collapsed. That makes me question not only his Ti (as dom), but points to his stubbornness as well, which is notoriously an Ni dom trait...
Then there is all the romantic stuff....which reeks of male infj.
