I had an experience teaching my grandma in her 90s some basic tech. There were no smart devices at that time and no assistants, but I'm pretty sure that assistant would not work for her. First of all because she is not English speaker, second because it is unpredictable tech, meaning that any query may end up in completely different result, which would block her.

Instead what she used most were stateless devices. Devices which you can turn off, then turn on, and then she would see the exact same starting point and have exact same path to the target. For example call on a dumbphone - she knew that she needed to unlock it via a corner button then press down on a joystick as many time as that person required. Same with TV, she knew approximately what buttons to click to get to some channel.

She had bad eyesight and it would make voice assistant even worse, because she wouldn't see what happened after each command.
