my quick shot he's similar to Linus Torvalds for me, has the same tone of voice and is less shy than him. 1:52 in that moment of the video who's talking are the eyebrows .__. for me he has Fi Te but i don't know what is above and what is under at the moment, and he seem J lead. 5:42 this seems a Si scowl. I don't know, for the moment i cannot go more under these videos, but for me is FiNe or TeSi. If FiNe: wow, another one who is in some scientific area, if i'm right i have to tell this to my brother
FiNe. He's got very naive-looking eyes and some sort of an inner glow that strong Fi users seem to have. Lots of personal smiles as well. Either FiNe or NeFi, but I'm leaning more towards FiNe because he seems to have stronger Fi than Ne. He looks down a lot and pauses which I think is because he engages in Fi. Also frequent eyebrow raises (Te) so I'm guessing that means that his primary oscillation is Fi-Te? That's what I see the most of, but I might be wrong about that since I don't really know how to tell what someone's primary oscillation is...
