Once the birds are in orbit, satellite internet is vastly superior to fiber in speed of deployment.

Fiber requires custom engineering at the city block level and a single rotten utility pole can block deployment.

I say this as someone who waited for fiber and is happily using it now.

So in Poland with Starlink I easily get 120 mbp/s but often in Kenya which I visit the maximum speed is just 10 mbp/s. Often the local 5g network is faster. The reason I believe that this is the case is dues to congestion on the Starlink network in Kenya. Ie. too many users in Kenya.
