Microsoft's Bing maps uses a huge amount of aerial orthophotos as well, not just satellite. Also aerial lidar for DEMs vs satellite radar data (the old srtm 1/3 for us48 states, etc).
I was just going by the trailer, which I'd imagine the Wikipedia page is citing, that references the azure AI and satellite data towards the beginning of the video.
My dream feature would be weather based on live meterological inputs.
You can have that right now for both X-Plane and Prepar3d with a very well made addon called Active Sky by Hifi Simulation Technologies.
Haven't they supported that for ages? I thought even FS2002 had that
