Yeah it helps the Ukrainians, but that’s the only valid use, and 4000+ satellites for basically only war seems like a bad idea. Cell phone 5G service will be cheaper in peacetime, and wartime has other communication platforms.
Uhh sorry but this line of thought seems pretty incoherent. Its use case clearly goes beyond just war (e.g. coverage of rural and wild areas where a land line or 5G will not be economical), since StarLink has gone online pretty much every global super power has started or announced building their own constellations, and during wartime you want to have as much redundancy in your systems as you can get, especially so in your lines of communication. And Ukraine is using it right now, during wartime. I can't follow this logic at all.
Well here is where my PhD in tracking stuff on paper, which gets handed out in triplicate to every German child at birth, comes in handy. The signature line customarily includes the date again because printing date and signing date (and thus validity) might differ. And yes, I know this is not applicable in a restaurant (hopefully), but that's generally the reason when it occurs.
