Bezos day late and a dollar short, or at least a successful in house rocket, he will never make the deadline to have enough working satellites in orbit.
It’s not so much the number of satellites in orbit, but the number that are visible from a given location and the bandwidth available. Kuiper sats are higher altitude and using Ka band which can offer more bandwidth.
He’ll probably make a go of it though. His main impediment is that he’s really just a salesman, rather than his engineering and programming educational background, and more concerned about making some kind of big name for himself.
I do wonder what will happen with the TVs and satellite mobile phones from Musk’s companies. I suppose we’ll see the Antifa and other leftist trash try to vandalize those as well.
