"[Luigi Mangione] followed a variety of accounts befitting a typically online young man — self-help gurus like Andrew Huberman, OpenAI’s Sam Altman, and 'heterodox' thinkers..."

"... such as Sam Harris and Richard Dawkins, as well as Joe Rogan. His strongest interest by far is in the work of Tim Urban, a writer and illustrator popular with tech types who publishes science explainers and anti-woke political writing about how polarization is bad and rationalism can save the world. There was one prominent exception to his innocuous online trail, though. Early this year, he favorably reviewed the book-length manifesto of Theodore Kaczynski, a fellow math whiz better known as the Unabomber, who killed and maimed people he believed had ruined the world with technology. 'It’s easy to quickly and thoughtless write this off as the manifesto of a lunatic, in order to avoid facing some of the uncomfortable problems it identifies,' he wrote. 'But it’s simply impossible to ignore how prescient many of his predictions about modern society turned out.' Mangione then quoted a 'take I found online that I think is interesting,' which ended by saying '"violence never solved anything" is a statement uttered by cowards and predators.' The manifesto found on Mangione is said to have stated 'these parasites had it coming.'"
