> If you work in a big city and look around; there are tall office buildings everywhere; packed with millions of people. But what do these people actually do? Is that an efficient use of their time in terms of creating value for each other? If you enjoy your current standard of living, then the answer is a clear, resounding "yes". You wouldn't be able to post on HN without the time investment of the people who created your browser, or maintain HN, or provide and maintain the infrastructure you use to post. > Maybe cryptocurrency is a bubble, but maybe also everything else is a bubble. Companies like Snapchat are worth billions of dollars, but they lose billions of dollars each year. That's an arbitrary example that supports your argument, but is not representative for the general economy -- in fact, it's entirely the opposite. Now compare your sentence to one where I substituted Apple for Snapchat: > Maybe cryptocurrency is a bubble, but maybe everything else isn't a bubble. Companies like Apple are worth hundreds of billions of dollars, and they make tens of billions of dollars in profit each year.
