Home Assistant almost goes without saying at this point.

Does it? I walk in tech circles, and actively work for a startup, and I don't think a single person in my circle of friends/coworkers has a Home Assistant setup, and _most_ have either an Alexa or a Google Assistant of some form.

Sure, but you didn't tell me that "no one in my technical circle has proprietary "smart" home automation devices". ;)

Home Assistant for home automation, Mycroft for voice control.

As others said - nothing (my preference), Mycroft, or Apple's Home Assistant (yes, propietary)

Thanks. I do however think that people are referring to home-assistant.io, not Apple Home Assistant.

Probably nothing.
