I think the offline ability will become king as a feature eventually - some of the other benefits might be:

- cost saving (like email send all at once using wifi spot while travelling and if not wanted to be subscribed by SIM card- just phone only comms)

- habits - doing things while not needing to be online (online means more tracking / opportunity for attacks being located on the Matrix). Making it more minimal overall.

- locally saved comms could be better/safe in certain use-case scenarios if encrypted / well self-managed rather than trusting other hosts to do it.

- offline behaviour change = less distraction and more focus on other things non-computer (much like email and dial-up days where we valued every second and just did it as a session rather than all day 'where did the time go' thing)
