They call it "AI", but I wouldn't be the least bit surprised if they've just run some basic pattern recognition on their stock of aerial GIS imagery, searching for blueish rectangles on land tagged as residential. It's probably the sort of thing that could have also been done 20 years ago or even more.
I used to work for Cognizant - they are very good at using the latest hype words to bag a client, so I fully agree with you. The same story from a different source was posted a couple of days back, and I said the same, simple pattern recognition can do this just fine.
It looks like there are two sides: people who want to buy a house and want it to cost a sane amount of money, and people who own a house and want it to increase in price. The latter would obviously ridicule this.
To me the problem is more the assumption that a pool automatically increases the value of a property. Or rather that increasing the value of a property should increase your tax burden. Insert sales pitch for Land Value Tax here.
