Honestly, I stand by my estimation that interplanetary communication will probably primarily be done over email.
It's just helpful to discussion if we don't assume others are expressing the stupidest possible iteration of the ideas they describe.
For example, my only means of accessing Twitter are either through the bloated Web UI, which is unusable on most of my devices, or through Nitter, which is read-only and sometimes doesn't work due to Twitter's API limitations.
In the context of interplanetary communication, sending the tweet from a server on mars to a server on earth would be a tiny packet containing a payload no bigger than the char limit, and some metadata. Browsing the website on earth would fetch from the servers on earth, and might still be 100KB, but no one cares about optimizing that bandwidth usage.
Idk if this is that much different from the original telegram at this point though. Sending tiny messages using limited bandwidth between two places. Eventually we'll widen that bandwidth sufficiently, it's just latency that probably won't ever surpass the speed of light. Also the problem of timestamping tweets when relativity is involved.
They'll even have netflix, if you think about it. Not youtube thought.
More seriously, I don't know why you assume Netflix would be accessible or a priority for settling on Mars - or that Youtube wouldn't be.
They just send one to Mars and it’s good to go.
For live transmission I think signal issues will cause everything to need to be pre-buffered basically to completion so streaming is not a realistic thing to consider. For instance, twitch is probably just flat out unless we have some pretty insane developments in general data transmission reliability (probably including FTL data transmission which, who knows, might some day be possible through entanglement).
A single tweet is so incredibly bloated and inefficient for transmission through space, that it would not have any chance of arriving uncorrupted on the other side.
"If you open that tweet in a browser, you'll see the page is 900 KB big. That's almost 100 KB more than the full text of The Master and Margarita, Bulgakov’s funny and enigmatic novel about the Devil visiting Moscow with his retinue (complete with a giant cat!) during the Great Purge of 1937, intercut with an odd vision of the life of Pontius Pilate, Jesus Christ, and the devoted but unreliable apostle Matthew.
For a single tweet."
