马斯克AI团队强推Grok入驻美国政府，敏感数据或成“训练料”引担忧
马斯克的政府效率部门（DOGE）团队近日在美国联邦政府内部强推自家的定制版Grok。据悉，Grok已被推荐给国土安全部等核心机构，尽管它尚未获相关部门正式批准。更让人担忧的是，马斯克和DOGE团队已访问存储数百万美国人个人信息的高度保密联邦数据库，这一做法打破了以往仅限少数官员访问高度保密数据的惯例，也让人质疑其合规性。
专家警告，Grok若未经正式许可就接触机密数据可能违反联邦隐私和安全法规，更让马斯克旗下xAI凭借独享的政府数据资源在未来政府合同竞标中占得先机。此外，有传闻称DOGE团队曾尝试利用AI识别员工政治倾向，加剧技术滥用与利益输送风险。

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
