【文/观察者网 柳白】 在美国，只要不是穷人就很安全？ 不一定。 最近这段时间，一个原本属于游戏世界的词，在中文互联网上迅速破圈——"斩杀线"。 在游戏里，当玩家角色血量低于这条线时，就能被一套连招瞬间终结。而在现实中，一名表面光鲜的美 国中产，实际血条却可能薄的像张纸。 但大量来自社交媒体的真实讲述——失业、疾病、房租、信用评分、保险拒赔——拼接出另一幅图景： 在美国，很多人并不是被一次灾难击倒，而是被一套连锁反应迅速吞没。 这正是"斩杀线"的含义：不是贫穷本身，而是系统在某个阈值之下，不再尝试修复你。 提到"斩杀线"的概念，离不开最近在美国被反复讨论的一种说法：在一些大城市，一个家庭年收入不到 14万美元，就很难称得上真正"安全"。 这并非官方贫困线，而是很多美国人自己算出来的"现实生存线"。 房租、医疗账单、保险……但凡个体财务状况、社会信用或生存资源跌破阈值，它们会像一套早就设计 好的连招，一起砸下来，让你"Game Over"。 从虚拟世界跳进美国社会，被赋予了冰冷生存内涵的"斩杀线"，成了无数普通人从体面生活坠入生存深 渊的生死线。 "斩杀线"，成了一种极具冲击力的现实隐喻。 美国芝加哥：官员查看 ...

Core Insights - AI is not leading to job losses but rather increasing the importance of radiologists, with demand for their services rising significantly [2][3][22] - The phenomenon of "Jevons Paradox" suggests that increased efficiency from AI can lead to greater consumption and job creation rather than reduction [4][12] - The "Baumol's Cost Disease" indicates that as some industries become more profitable due to efficiency gains, wages in other sectors must rise to retain talent, leading to increased costs across the board [16][18] AI in Radiology - Over 700 radiology AI models have received FDA approval, representing more than 75% of medical AI devices [22] - By 2025, the average salary for radiologists in the U.S. is projected to reach $520,000, making it the second-highest paid medical specialty [2][22] - The number of positions in diagnostic radiology is at a record high, with a vacancy rate also reaching historical levels [22] Economic Implications - The rise in AI efficiency is expected to increase service costs in unrelated sectors, as wages rise to compete for labor [18][20] - AI's impact on productivity may lead to a paradox where jobs that cannot be automated become more valuable, as they represent the final human touch in processes [21][23] - The overall economic growth driven by AI may lead to a situation where even low-skill jobs, like dog walking, become more expensive due to rising living costs [20][21] Future Workforce Dynamics - As AI takes over 99% of tasks, the remaining human roles may become highly specialized and valuable, leading to a unique labor market [21][23] - The potential for new job categories may emerge, focusing on tasks that require human presence or decision-making, despite the automation of many processes [23][24] - The ongoing challenge will be to enhance productivity while managing the societal changes that come with technological advancements [24]

想不到一向"浓眉大眼"的迈瑞，也"暴雷"了。 4月28日晚间，在迈瑞医疗公布年报和一季报后，股吧和雪球的讨论区便瞬间炸开了锅。 迈瑞医疗2024年营业收入367.3亿元，同比增长5.1%；归母净利润116.7亿元，同比增长0.7%，剔除 财务费用影响后的增速为4.4%；经营性现金流净额124.3亿元，同比增长12.4%。 2025年第一季度，公司实现收入 82.37 亿元，同比-12.12%；实现归母净利润 26.29 亿元，同 比-16.81%。 对于常年保持20%增长的"好学生"迈瑞来说，这张连续两个季度业绩miss的成绩单，还是有些过于"惊 喜"了。 但出乎大家意料的是，4月29日开盘之后，迈瑞医疗在小幅低开以后迅速冲高，收盘微涨。考虑到最近 A股对于业绩不达预期这事比较敏感，更显得难能可贵。 由此可见在一季报中"前低后高，逐季改善"的业绩指引，还是赢得了机构投资者的信任票。 而除了实实在在的业绩数字之外，迈瑞医疗的数智化转型，在更高的维度上决定了企业的未来。 从"数据孤岛"到"智能生态" 从ChatGPT到DeepSeek，从IBM Watson到AlphaFold3。没有人可以否认，全球医疗行业正在 ...
