Earlier quoted context omitted.
If I understood it correctly Starlink doesn't send between satellites yet, only sat ground. Sat sat is a big point of starlink and when they roll that out the latency should go down, especially for starlink starlink comms I imagine.
Yes that’s a few more years before then, and the more sats the more capacity and the lower the latency.
Judging from their high launch cadence, it seems satellite-satellite communication was just a means to excite the fanboys and motivate their employees, the same way the peddle the Mars stuff.
