Stream implementations can and do ignore backpressure; and some spec-defined features explicitly break backpressure. tee(), for instance, creates two branches from a single stream. If one branch reads faster than the other, data accumulates in an internal buffer with no limit. A fast consumer can cause unbounded memory growth while the slow consumer catches up — and there's no way to configure this or opt out beyond canceling the slower branch.

The numbers tell the story. ChatGPT reached 100 million users faster than any consumer application in history, hitting that milestone in just two months after launch. By early 2025, ChatGPT alone processes over 10 million queries daily through its web browsing feature. Perplexity has grown to millions of daily users who rely on it as their primary search tool. Google has responded by launching AI Mode, available in over 180 countries, which provides AI-generated answers above traditional search results.
贝恩咨询预测，在温和情景下，未来AI推理基础设施支出可能下降30%-50%。这正是杰文斯悖论的反向演绎：通常情况下，资源使用效率的提升会增加总需求；但在AI领域，当算法优化的速度超过应用落地的速度时，效率提升反而先冲击了硬件供应商的定价权。
