They actually aren’t done well via voice UI either - if you care about the output.
We just gloss over the details in these hypothetical irregular or abstract tasks because we imagine they would be done as we imagine them. We don’t have experience trying to tell the damn AI to not delete that cloud (which one exactly?) but the other one via a voice UI. Which would suck and be super irritating, btw.
We know how irritating it would be to turn the shower off/on, because we do that all the time.
