My hope is that galaxy wide telepresence disappears when space legs becomes a thing.Telepresence is not that bad. It's simply a hologram (already have that with the HUD, definetely not lore breaking) and some remote control. Sure, why can we use remote control over several hundred ly's but not transfer exploration data and stuff? No idea, probably for game play reasons. But this inconsistency was already in the game since Galnet and basically everything else. The question is, why do we even need to fly our ships if we could just use telepresence instead? Maybe this will make more sense when space legs arrive.
Galnet is an issue, but not as bad. It could one way traffic. Would be low latency and would need very little security compared to the direct link into your brain.
But saying that, I would prefer galnet updates when you dock at a station. Don't really need it when I'm 40000 Ly away.
