WebAssembly Is Ready for Mobile. Apple and Google Are Not.
WebAssembly and WASI promise a secure, portable future for software, but the moment you target mobile, you hit a wall. Running WASI on iOS or Android requires userspace hacks like Termux, sacrificing true OS-level sandboxing. This isn’t a technical failure; it’s deliberate gatekeeping. If mobile OSes supported WASI natively, developers could bypass app stores completely, destroying Apple and Google’s 30% toll booth.
