经济合作与发展组织:测试显示全球认知能力下降,AI兴起或加剧趋势

经济合作与发展组织(OECD)的国际学生评估项目(PISA)数据显示,自2010年代初以来,全球青少年的阅读、数学和科学能力普遍下降。2022年数据显示,美国阅读能力显著下滑,近50%的成年人几乎不读书,每天阅读的比例降至14%。

不仅是青少年,成人的认知能力也在下降。高收入国家约25%的成年人在简单数学推理和判断语句真实性时感到困难,美国这一比例高达35%。研究认为,这种趋势与现代生活方式有关,如被动接收信息(如刷手机)而非主动思考。

此外,生成式AI的兴起可能进一步削弱批判性思维。微软和卡耐基梅隆大学的研究发现,过度依赖AI会导致“机械化趋同”和“数字健忘症”,影响认知能力。

How to Invest in Bitcoin?

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.”

That growth environment will include rising inflation and interest rates. Those upward shifts naturally accompany healthy growth periods as the demand for resources, products and services rise. Importantly, the Federal Reserve has laid out the rationale for not interfering with that natural growth transition.It's not exactly a fad, but there is a widespread willingness to pay up for a growth story. Classic fundamental analysis takes a back seat. Even negative earnings are ignored. In fact, positive earnings seem to be a limiting measure, producing the question, "Is that all you've got?" The preference is a vision of untold riches when the exciting story plays out as expected.
