While not perfect, I'm sympathetic to the hippies not only because of my two Summer of Love aunts, but because in a tough world, they dared to question the imperfect status quo and attempt to try to make something better than just accept the bad.

But the mindset wasn't a total wash. After all, they were right about the Vietnam War, weed, civil rights, magic mushrooms, and they're part of the reasons we have Silicon Valley, iPhones, and open source. It's no coincidence YC / HN is based in the exact locale the hippies were.
