社交巨头 Meta 下载了盗版电子书去训练其 AI 模型，最新证据显示 Meta 的盗版规模惊人。Meta 通过安娜的档案（Anna's Archive）下载了至少 81.7 TB 的数据，其中包括来自 Z-Library 和 LibGen 的至少 35.7 TB 的数据(安娜的档案包含了 Z-Lib、Sci-Hub 和 LibGen 的镜像站)。Meta 之前还从 LibGen 下载了 80.6 TB 的数据。图书作者称，Meta 非法的电子书库种子下载规模惊人，认为这只是冰山一角，这些盗版电子书库仅占 Meta 盗版版权作品数量的 0.008%。
提供大语言模型数据这可能是「安娜的档案」项目实现收入的途径之一。🌚

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
