Starlink direct to cell will still cover huge areas per cell which is great for remote areas but not for high density like cities. It will not have strong enough signals to penetrate buildings. And it won't provide enough bandwidth for more than texts at least not for now.
It's an augmentation of the land based service, not a replacement.
Hopefully this will bring back website that is focus being on being lightweight, and just display information (or gemini type of alternative), and discourage the SPA development fiasco that has happened.
If you download all the UI elements, layout, and styling up-front, and then only have to communicate with the server to fetch structured data that tells the app how to change the user interface, that's strictly better.
The issue, of course, is that most pages (regardless of whether they're SPAs or not) require a large amount of bandwidth to download assets.
But I would expect that a low-bandwidth SPA would be more responsive than a traditional low-bandwidth website where it has to reload the full page every time you do something.
Or - as a user - the LocalCDN addon
Not 'back'. This is normal for satellite data other than static Starlink installs with their huge antenna. The iridium Go! Hotspot does about 2400 bps :) they also have a new note expensive version that does up to 88 kbps download and 22 up. Still dialup speed so?
