Jeez, when visualized like that, that's a lot more than I was expecting. How many multiples of this do they currently expect they want to get their vision of a general service running?

Maybe a dumb question, what are the ones that seem to be a bunch in an arc/line? They seem to be a somewhat continuous-ish numbered ones, but not very strictly.

Is the latitude limited by physics or just their limited operation? I know the really great case for this is more remote areas, but just wondering like the Nordics, Moscow. Doesn't get much more remote than Siberia. Are they just out of luck?

Probably dumb questions, don't know much about space flight, just kind of astonished by the amount of satellites. I kind of wish it made more sense for me when it becomes available. My internet's okay, but my area is probably populated enough I might not be the target audience, or a place where it works out well.
