Amazon likely does have big future plans for sidewalk. It occurred to me that they could use it as a wifi "hotspot" for Kindle users to buy books over. It's a low bandwidth functionality. It would make 3G less necessary.

Regarding things like Alexa, voice transmission is very low bandwidth these days. That would work too. Sidewalk has countless potential uses that would multiply the wider the network is.

I wonder how deep is the penetration of Amazon and potential sidewalk devices is. It's 46.5 million Echos in the USA. Then there are Shows, etc. I wonder what other Amazon internet-activated devices there are that could be piggy-backed? What about Kindles? And that's just Amazon. Echos have only about 50% of the market.

It's interesting technology, and I can see why it makes some people uneasy about privacy. Obviously the government, and other entities, will be able to access these devices. The web is growing and becoming more detailed.
