I am sure Elon doesnt realize that this will never work as well as he thinks it will. But then again, throw enough money at a problem and it will get fixed eventually.
There is an inherant issue with satellite systems and unless someone knows how to bend the laws of physics to escape the speed of propgation for radio signals, the delay even on LEO and Fast-LEO is still orders of magnatude larger than a decently run WISP network. You can offer 5 and 10Gbps links all you want, but if the delay is 250ms or more each way then its better to look at your WISP.
I made Vonage work over Xplornet's old Ku system, but it wasnt pretty or good. People wont tollerate that anymore. Just look at LEO companies like Iridium (defunct) and Globalstar(still doing sat phones and now doing two way GPS locator and remote T1 service).
I am not overly worried about StarLink yet and when asked about it I answer honestly with the comparable information. "We can not access it here yet, but you can access our network now. The current advertised speeds in a coverage zone is XX (we look this up with the client so that it is up to date and acurate) for $YY per month. We can offer you speeds up to AA for $CC per month, with no data cap. We own the hardware so you do not have to worry if it fails (we get lots of ESD in our area) and we are local so you dont have to wait for a tech to come from ZZZ." We try our best not to offer opinions as the facts speak for themselves: it takes time for data to travel and though a satellite can cover a very large area or traverse long distances easier, there is a reason why terrestrial wireless and fiber optics are being installed. Without including network delays, it takes 125ms just to get to Anik F1 if your on the equator directly below it, then make the trip to the earth station. Now return! Flawless hand-off on mobile systems is still a troubling thing, getting better but when is the last time you roamed between cell towers and didnt have a glitch! not do that every 30 seconds as old satellites fly past the horizon and new ones come up.
I personally think this is a fad thing that will leave hundreds of satellites to fail and fall, at least it will be pretty when it happens :) And this is My opinion.
