You may be familiar with the Amazon Alexa family of voice assistant speakers like the Echo.
We are literally heavily invested in Alexa technology here. Back when we first returned from Hawaii when I was using a walker there was a floor lamp in my office that was difficult to reach. So we connected it to an Alexa-capable switched outlet so I could say "Alexa, turn on the office light." and there would be light.
This "morning", actually more like 11:30PM when I woke up from my brief night's sleep, Alexa was unable to turn on the light because our Internet connection was down. I found that our router locked up, rebooted it, then I was able to turn on the light.
This episode illustrates the fact that the more complex a system the greater the chance of failure. Wall switches tend to be highly reliable by comparison.
