Chrome OS was far ahead of its time, both in its general user hostility and in its excessive resource consumption for seemingly mundane tasks. Like when your roommate's YouTube streaming makes your Excel-like app horribly slow, because your new spreadsheet app needs high-speed internet for no obvious reason.
BTW, WebRTC and WebAssembly were great for crypto mining trojans embedded into ads. Before, they had to port their crypto miner to JavaScript by hand. By now, you can just cross-compile it. The progress of technology ... helps only the technology, but not you, the disposable user in front of the screen :p
