It&#x27;s crazy because, apart from performance concerns (it looks like we <i>love</i> to make our computers slower and slower every 10 years), you&#x27;re just discarding all the features of the containing desktop OS. Formatted copypasting, usability features, network features, etc etc... you&#x27;ll have to reimplement them all, solving all the problems that systems developers solved 10 or 20 years ago. The OS will become little more than a very expensive pixel pipe. But that&#x27;s what people like, because C++ is hard, native widgets are hard to customise, and everyone loves designing interfaces, so that&#x27;s where we&#x27;re going.<p>I anyone ever starts making javascript-optimised CPUs and GPUs, they&#x27;re going to make billions. At the moment we only have micropython, but who knows...
