> Having a voice assistant means not having to learn to change application contexts inside an operating system follwed by a few seconds typing. You are ignoring the hundreds/thousands of hours you've spent learning which software is appropriate for which contexts. Not to mention the latency of instantiating them, or possibly even installing them, migrating data between them, etc.
I can type everything I'd issue as a voice command into my home screen. I have to install and learn just as few/many things and commands as I'd have to using voice recognition. Op might have underplayed something, you just made things up.
