Same with electricity: there are many rural places in Africa where solar panels + batteries are a revolution.
But then there's a reason why a country with more than 3x the number of people in the US was "missing" technologies: Africa is, overall, very poor (GDP per capita in Africa is something like 1/40th of the GDP per capita in the US: 1/40th!). So there's a limit to how far the jump is possible: as someone commented, most of Africa is still on 3G and it's not clear if StarLink shall be able to find customers rich enough to buy their services.
