And it is starting an additional emulated x86/amd64 vm that is emulated. The battery takes a big hit. Now imagine you can run wasm that doesn‘t need an extra vm and doesn‘t drain your battery much faster.
I think the # of people losing a lot of of battery to this is miniscule, especially since the OSX x86 emulation is pretty fast.
A bigger peeve is that there is no general reasonably fast cross build ability, to eg build, test and debug ARM images (for runnign on ARM servers) on x86 Linux or Windows etc.
