While I agree that ATC, Weather and ground handling definitely need mayor focus, I'm not sure it's the same story when it comes to scenery. He should focus on fixing those items while "the community" (freeware and commercial) keeps improving the scenery situation.
I'm not in the FS2020 alpha, so I cannot comment how much of an improvement this new technology really brings to ATC and weather (although from the looks of it, weather and atmospherics in general look amazing). When it comes to scenery, it's even harder to know how places outside of Europe and the USA are treated by this Azure AI thing. X-Plane has relatively easy to use tools to develop scenery, and the concept behind the gateway (while far from a FlyTampa airport in terms of quality or detail) offers a much better chance of basic but updated coverage in comparison to P3D.
On the other hand, if Asobo provides powerful tools and simplifies the process of scenery creation and creates some sort of "gateway" for keeping scenery/airports up to date, then this would help providing coverage to places where the high definition scenery is non-existent. I'm talking Africa, some parts of Latin America and Asia where I'm sure photogrammetry is out of the question.
