That being said, it would be interesting to see what happened if all of, say, Lagos (fastest-growing city+suburbs in the world) suddenly started using Starlink exclusively.
"Good things" is not very high on my list...
So in general it's good news for the rural population (if they can afford it), but it doesn't really help too much for the cities.
That's very much not what the Starlink-proponents are, loudly, proclaiming. Because, satellite-peer-to-peer stuff, Elon-magic in general, and whatever.
Please note: I think that Starlink is mostly space pollution, and that offering meaningful Internet connectivity to Africa, or rural America, or anywhere mostly involves 'lots of fiber', some radio, and lots of cooperation.
But: "just get your Starlink dish and be done" is definitely an Internet Truth, and it's Wrong, and I think it's worth Pointing Out.
The government has already provided many rural schools with Starlink terminals, and many locations which only recently didn't have internet connectivity now do have it. Apparently they don't see something you do.
Are these places covered by "POTS" copper telephone access?
So, while technically very interesting, and providing some value before it all comes inevitably (and literally -- see: space junk) crashing down, all that talent and money spent on Starlink would better be put to use elsewhere.
But unfortunately it's easier to get investment for space dreams than for running fiber, even though it's the latter that's mostly needed, and despite plenty of success stories.
