Most revolutions have been silent revolutions. The only one that was an instant world event was the iPhone launch. All the technologies named in the article; Wifi, Google Search, Facebook, Twitter, even YouTube and Wikipedia were not introduced to millions of people at once in a Silicon Valley event. AI will change the world, but it'll be slow, like how the internet changed the world little by little replacing retail, letters, phone calls, and now maybe 40 years later, TV. AI is a process revolution, not a product revolution. So he's right, big tech products have been mostly useless, specially compared to their promises.
