I don't agree with the thesis here. As somebody whose day job involves tracking "hacker groups" in the adversarial sense and whose hobbies largely involve belonging to "hacker groups" in the doing-cool-shit sense, I feel like there's an assertion with precisely no evidence to support it.
Also, statements like "We live in days of limited creativity" strike me as extreme nostalgia and conservatism. We live in days of INCREDIBLE creativity, in my view.
