Net international migration to the U.S. peaked at 2.7 million new entries in 2024, but has since sharply declined. It fell to 1.3 million last summer, according to January Census data, and then turned net negative, according to research from Brookings, meaning more people are leaving the U.S. than coming in. The private sector has weighed in, too, with Goldman Sachs economists reporting last week that immigration policies put in place over the past year have resulted in an 80% decline in net migration relative to the historical average.

In recent years, LLMs have shown significant improvements in their overall performance. When they first became mainstream a couple of years before, they were already impressive with their seemingly human-like conversation abilities, but their reasoning always lacked. They were able to describe any sorting algorithm in the style of your favorite author; on the other hand, they weren't able to consistently perform addition.

This created the belief that with enough scaling, LLMs will be able to learn general reasoning.

从公元前600年左右起，欧亚大草原上的人们开始掌握骑术。到公元前400年左右，与农耕民族交界的北方游牧部落将骑马与射箭相结合，形成了一支马背上的强大军事力量。骑兵出现后，农耕民族与游牧部落之间的贸易活动和文化交流日益兴盛。无论是赵武灵王的“胡服骑射”还是秦汉长城的修筑，都与来自欧亚草原的骑兵密切相关。骑兵尤其是重装骑兵的出现革新了战争形态。文献记载的“甲骑具装”，为将士和马匹都披上厚重铠甲，可如同坦克一般冲锋陷阵，所向披靡。湾漳壁画墓出土的甲骑具装俑（见图）便是这一兵种的真实写照。近年来，在邺城正南门朱明门外的护城河中，意外发现了一具保存相对完好的“甲骑具装”铁铠实物。当时能够编入军队的这类兵种数量或许还相对有限，也存在一些马身未披铠甲的骑兵。
