其一，依托自研芯片对冲成本压力，掌握定价主动权。正如文章开头所言，当前整个PC行业的最大痛点，便是厂商高度依赖第三方供应链，核心芯片、存储元器件的定价权牢牢握在上游供应商手中，内存、闪存涨价，下游厂商只能被动承接，要么涨价丢市场，要么保价亏利润，陷入两难死局。而苹果凭借垂直整合的产业链优势，用自研芯片跨界复用的方式，实现成本自主可控，跳出供应商的定价绑架，这不仅是苹果自身的破局之路，也给整个PC行业敲响警钟：掌握芯片这一核心硬件，才能在成本波动的市场中站稳脚跟。

Notice that these “serial numbers” are very similar to the ones we embedded in the single-use credentials above. Each Resource (website) can keep a list of each SN value that it sees, and sites can reject any “show” that repeats a serial number. As long as the User never repeats a counter (and the PRF output is long enough), serial numbers should be unlikely to repeat. However, repetition becomes inevitable if the User ever “cheats” and tries to show the same credential N+1 times.
Earnings data suggests to Goldman that localized productivity gains are already beginning to influence corporate hiring strategies, leading to a “nascent reluctance to hire in anticipation of potential productivity gains.”

Many recent papers labeled as “reconstruction” are effectively performing n-way decoding: they decode a category and then use a generative model to produce a visually plausible sample inside the predicted class. This can look convincing, but remains a restricted classification problem. Similar n-way decoding setups have long been standard in the MVPA literature and can achieve quite high performance when the candidate set is limited.
