Edit: To clarify:
Is it even possible, financially speaking, to keep adding storage? I mean, advertisements don’t even make a lot of money, is the indefinite growth of server storage even sustainable?
Or will they do what Twitch does with old content and just delete them?
I have wondered the same from time to time, but I really don’t think so, every time tech becomes better and smaller (for the most part), it wouldn’t be crazy to think we can double or triple the current amount of normal storage we have in a few years, without compromising size at all, and Google has the funds to adapt these new tendencies first than most folks.
