> It'll be nice to know that any normal PC program we write will "just work" on Raspberry Pi and Apple ARM. All we have to do embed an ARM build of the emulator above within our x86 executables, and have them morph and re-exec appropriately, similar to how Cosmopolitan is already doing doing with qemu-x86_64, except that this wouldn't need to be installed beforehand. The tradeoff is that, if we do this, binaries will only be 10x smaller than Go's Hello World, instead of 100x smaller.

…No mention of the fact that an interpreter is typically at least 10x slower than native execution. The readme does say "we're still likely to add something like jit in the near future", but for now this isn't very practical.
