VIM is well designed and stable, so you can learn the interface and be confident that it will work for you next time you use it. It's an amazing tool.

Today's voice assistants are the opposite. They are unreliable and completely unstable. They don't have a clear list of commands they understand, let alone some sort of menu system - the documented commands on the manufacturer's websites often don't work. They also randomly change what they can do: stuff stops working for no obviously reason.

For example - yesterday, my son's Nest Audio suddenly refused to set a music alarm, claiming "this device doesn't support that feature yet" (it's literally a speaker for music...). It worked the day before.

So the problem is with lack of documentation and unstable UI, not with the lack of discoverablility per se.

Identifying the problem is often the first step in fixing it.
