Happened the other day on HN. "Imagine we could use this to stream movies to astronauts on their way to Mars" / "well... you know local storage is a thing, right?".

I don't have a link to that exchange handy, but this for the first time drove home to me the realization that we have a whole generation of people brought up on Internet streaming services, who may not even realize that it's not only possible for the media to be stored locally on their machines, but it's in fact the natural state for data.

And we'll need a programming language that we can write our application in once but will still run on the different operating systems.

We are lucky that physics is limiting the latency and bandwidth of the internet, since otherwise local storage could truly disappear.
