When I were a nipper lag/latency over 30ms was considered a bit crap for voice unless satellite links were involved. That's for circuit switched networks. Human conversation works best with a sub 25ms latency and you will start to notice lag at 30ms.

Nowadays with all our massively more powerful links (Gb vs Kb) but packet switched, we often end up resorting to a form of half duplex radio protocol. That's just voice, let alone video.

That's what you get when you abrogate your comms to a hyper scaler that will never scale to the point of what you would like because it will damage profits upstream.

Whilst your end will be a phone or laptop or whatever - with gobs of capacity, the hyper scaler bit will be woefully under powered for your call but just enough to keep comms going and your subscription dumping cash into the coffers.

You end up re-inventing how to talk to someone over a satellite link in the 1970-80s ... in 2026! I (UK, 55 y/o) can clearly remember my parents telling me how to talk to great aunt Maye in Australia on the blower. Nowadays we have the internet to packet switch instead of circuit switch which is generally capable of ~10-50ms latency nearly anywhere, where mostly copper is involved. However call quality seems to be shit!
