“According to technologist David Rosenthal, speculation on cryptocurrencies is the engine that drives Web3—that it can’t work without it. “[A] permissionless blockchain requires a cryptocurrency to function, and this cryptocurrency requires speculation to function,” he said in a talk at Stanford in early 2022.4 Basically, he’s describing a pyramid scheme: Blockchains need to give people something in exchange for volunteering computing power, and cryptocurrencies fill that role—but the system works only if other people are willing to buy them believing that they’ll be worth more in the future. Stephen Diehl, a technologist and vocal critic of Web3, floridly dismissed blockchain as “a one-trick pony whose only application is creating censorship-resistant crypto investment schemes, an invention whose negative externalities and capacity for harm vastly outweigh any possible uses.”

“Decentralization makes technology more complicated and further out of reach for basic users, rather than simpler and more accessible. While it’s possible to fix this by adding new layers that can speed things up, doing so makes the whole system more centralized, which defeats the purpose.”

“In the beginning, there was the internet: the physical infrastructure of wires and servers that lets computers, and the people in front of them, talk to each other. The U.S. government’s Arpanet sent its first message in 1969, but the web as we know it today didn’t emerge until 1991, when HTML and URLs made it possible for users to navigate between static pages. Consider this the read-only web, or Web1. In the early 2000s, things started to change. For one, the internet was becoming more interactive; it was an era of user-generated content, or the read/write web. Social media was a key feature of Web2 (or Web 2.0, as you may know it), and Facebook, Twitter, and Tumblr came to define the experience of being online. YouTube, Wikipedia, and Google, along with the ability to comment on content, expanded our ability to watch, learn, search, and communicate. The Web2 era has also been one of centralization. Network effects and economies of scale have led to clear winners, and those companies (many of which I mentioned above) have produced mind-boggling wealth for themselves and their shareholders by scraping users’ data and selling targeted ads against it. This has allowed services to be offered for “free,” though users initially didn’t understand the implications of that bargain. Web2 also created new ways for regular people to make money, such as through the sharing economy and the sometimes-lucrative job of being an influencer.”
