why stream on demand if we have the bandwidth to just send the whole video in the first 100ms? this might actually save power; instead of back & forth back & forth with the service, we can transmitnthe whole thing & be done, the server can now go serve other people.

Probably the best argument would be that many/most? people don't watch the whole video.


I can't find it right now but I remember reading a paper by Cerf? (I'm not great with names) that detailed such a concept. If I remember it I will edit and post a link.


Because then you have to cache the whole thing to disk, probably SSD, and increase the wear rate there unnecessarily...


SSD wear rate is not a concern
