Absolutely INTP, i am an INTP and he is exactly like me
But the thing with him is that his P is really low, he is a strong introvert, average N , strong T and low P
Those who doubt of him being an extrovert are wrong because even in his face you can see the introversion
He is a typical INTP ,searching for the truth, he can not be J because the work he does is very P in its nature, the topics which he studies are so spontanous and dont really have a row of which should be first and which last, he just sort of posts videos of whatever insight he experienced which is also a typical INTP thing, they like to talk about the things which they experience and learn, INTPs love to share their ideas and knowledge with other people, and an INTJ is very different from that.
