The other, gigantic shoe that will someday drop will be Google transcribing every incidental conversation. It can already do that, on-device, for every song that's heard, ever. It's a super power, being able to remember every word spoken around you, time and place, but of course it has privacy implications even if all the work is done without their cloud.
I've noticed a trend in older folk where they get halfway into a sentence knowing they don't know the name of what they are referencing only to ask those around them for help identifying the reference on the way to making some other point, e.g., "That's like that time in It's a Wonderful Life where _______, gosh, I can't think of his name. What was the guy that was in that movie? Oh yeah, James Stewart. That's like the time in It's a Wonderful Life where yada yada yada"
I'm hopeful that voice recognition assistants will help the burden during Christmas visits :D
