Telephones have been around for a very long time. Do you mean pre-cell phone era? If so, I mostly disagree. Especially before email and then all manner of messaging services became popular it was incredibly normal to call people out of the blue both for both personal and business reasons.
When I was a product manager, field people would often call me with questions rather than email. My personal observation is that it's really within the last ten years (and maybe less) when people outside your immediate circle really stopped calling unless they connected asynchronously/scheduled first--and increasingly did away with phone calls entirely in many cases.
Pre-CallerID especially, a lot of people were conditioned to a phone call being something important that took a long time to break.
Of course, calling was relatively expensive so while you could have wrong numbers you mostly didn't have junk callers.
As for turning on the oven remotely. I'm old enough to remember when oven timers were actually used, for the simple reason that not every household had a microwave. Our particular use case: We four kids came home on the school bus to our rural house, and parents were gone to work at the other place. Dinner was in the oven, timed to be heated up and ready to eat when we got home. With a good half hour to budget to go from cold (or room temperature) to piping hot, the timer made sense. Now it's just 3 or 4 minutes in the microwave and done.
I remember my dad purchasing a speech recognition package in the early 90s, but it ran on an expensive 486 desktop machine and was reasonably but not accurate enough for his uses.

That sounds like a safe feature!
The other is the family casserole that we used to have on a Friday night. My parents would prepare it in the morning and program the oven to come on at a low temperature at 15:00. Then when we got home it would be done perfectly.
There are others, those are just the two of which I have direct personal experience.
Unattended start for a gas oven does feel dodgy though.
Yes, actual video with start index:

Thank you.
I know "Hey Siri, call my wife" works. If you've got your contacts set up with relationships and nicknames, it works really well. I use it regularly while driving, both with voice calls and text messages.
