HN has been obsessed with this project for the past few days, and that might be why you're getting so aggressively downvoted. Cosmopolitan is interesting from a technical perspective, but doesn't really bring anything new to the table. Packaging multiple entry points in the same file is a clever hack but is extremely brittle (for example, archiving/re-archiving can mangle relevant sections which ZIP doesn't care about -- this will break your binary), ELF uses a pre-processing step which renders the binary non-portable once it's run, and the cross-platform libc stuff has been done since time eternal. Not to mention that, as you say, just C is nigh useless these days, anyway. It's kind of funny to see people comparing this to Electron.
