So if you read into Kaczynski a bit, in a way he's kinda history's first incel too. He went off into the woods because he was upset about getting rejected by a girl and went super nice guy™ on not just her but life too. He blamed technology on his inability to read into a woman and he was too insecure to learn from it.
This guy is doing something else, he attacked the elite not because of technology and their relationship but because of their wealth and direct actions.
This kid is from wealth. It seems very wealthy. Not country club money but country club owner kind of money. Its more likely for fame and getting in the history books
