I don’t have any of those devices, but I do have fun with the devices in other peoples homes by telling Alexa to set an alarm at 3 am and to make a rooster sound! I didn’t think it would work but it did! My oldest son never figured out it was me that did it.

I wouldn't have one of those things in my home, even if I were paid to.

I don't know anyone who has one either.
Wouldn't step foot in a house with one.

All I got now is my nest thermostat. I do have one of those small Google things (echo? dot?) and I can set temperatures from my phone. That's about it. Some of my kitchen appliances don't even have three prong plugs.

"Approximately there are around 7.62 billion humans on our planet, but to your surprise, by the year 2021 with an increasing graph of IoT devices, there may be around 20 billion IoT smart devices up and running with an increase in the demand of 5g network."

No. I don't trust the systems or the companies that operate them.

It's a good thing I never have guests except family, then I know who to feed that to every time they visit.

Nope but the idea of automation is nice

No. Mainly because I have more important things to spend money on.

Two garage door openers, thermostat, irrigation system, a PTZ camera with two way audio + IoT from my car.

It make my life easier.

Just choose strong usernames and passwords and use MFA.

And I don’t use the digital assistant as they are way too intrusive.

None for me. I don't own Alexa, and the "digital people" that came with my Windows 10 (Cortana) and my iPhone (Siri) are deactivated.
