How can Amazon monetize a map of my home? If it's so valuable, then are there other companies recreating the map from public data (ie real estate pictures, county data, etc).
There will be, there will be.
Well I my opinion the one area that Amazon is not doing so well is supplying home decor products. Ikea and other platforms are much bigger, I believe this is the area where Amazon sees a huge market potential. Understanding what size of room does individuals have could give Amazon that edge of supplying so-called "made for only you" furniture. The entire space of personalised products and marketing is growing by leaps, understanding someones home could do wonders for Amazon. And not only in home decor space but I guess this will also help to enhance its current offerings such as improving Alexa's connectivity within the house, smart light illuminance etc.
