I would be hard pressed to say computers & the Internet are a net positive for the world. For me personally, they unlocked a passion & interest I haven't been able to find in any other domain. I have plenty of other interests & loves, but anything to do with computers is my passion.
For the rest of the species, where a computer is either a means to an end, a necessary evil, or a way to brainwash yourself, I don't view computers as something beneficial. The undiscerning get sucked into YouTube black holes & allow themselves to be swept up by bullshit they read on Twitter. It gave a platform to the absolute worst people among us, which would be fine if people would reject the garbage they're spouting.
Our collectively stupid ape brains aren't ready for computers. I believe we (the royal "we") moved too fast & poisoned our shared, objective reality. And that's all before I even start talking about the people intentionally making life worse with technology. Your Zuckerbergs & Musks & Ellisons, the people who use these machines as tools to spread suffering & chaos.
