But after years of building on Web streams — implementing them in both Node.js and Cloudflare Workers, debugging production issues for customers and runtimes, and helping developers work through far too many common pitfalls — I've come to believe that the standard API has fundamental usability and performance issues that cannot be fixed easily with incremental improvements alone. The problems aren't bugs; they're consequences of design decisions that may have made sense a decade ago, but don't align with how JavaScript developers write code today.

初期科室很简单：手术科、诊断服务科、麻醉科，还有1973年独立出来的护理协调部门，主要提供急诊、心脏护理、手术和康复服务，床位也从最初计划的61张，扩展到355张。为了贴合老人需求，医院还引入了家庭护理项目，把顶层空间改造成健康教育等多功能区域——本质就是“老人需要什么，就补什么”。
This almost certainly won’t happen to the ISS. At the same time, it’s a far more extreme version of the only way an American space station has ever come down. In 1979, after years spent vacant in orbit, Skylab, the US’s first space station, started sinking toward the atmosphere, where it threatened to fall and drop molten spacecraft parts on Earth. At that point, NASA officials had to remotely wake up its computers and, with only limited control of the station, direct it over a location that would endanger the fewest humans.
