I had casually typed Elon Musk a while back but upon revisiting it i'm seeing something else, so thought I would drop it down here for others input as well.

Elon disengages down a lot(Ji), and his smiles on occasion seem interpersonal(Fe), and his eyes have such a strong Se look to them that I was initially leaning towards TiSe but then I started seeing his Te/Fi closed fingered gesticulations, his giddy "ha ha ha" Fi laugh, his eye centricity, snippy head nods, etc.. and I thought maybe NiTe is better. NiTe still isn't crystal clear to me but it's my best guess and i'm pleased to see you fellas have also typed him that way.
