^ This.

Growth in this context is that there are a larger volume of videos each year. So each year a single video is exponentially a smaller and smaller percentage of the total.

Yeah and the math doesn't check out.

For example, if in year N youtube has f(N) new video. Let assume f(N) = cN^2. It's a crazy rate of growth. It's far better than the real world Youtube, which grew rather linearly.

But the rate of "videos that are older than 5 years" is still faster than that, because it would be cubic instead of quadratic. Unless the it's really exponential (it isn't), "videos that are older than 5 years" will always surpass "new videos this year" eventually.

Such a weird strawman argument that you are making up. You've over thought this so much that you are missing the forest from the trees

Video sensors are continuously getting cheaper, better and more more prevalent over time. The trend is towards capturing all angles of everything, everywhere, at increasingly higher resolutions.

Yes. a video no one watches is a waste of storage.

Maybe not.

Maybe it could be used to train a neutral network. Maybe it contains dirt on a teenager, who might become a politician two decades from now. Maybe it contains an otherwise lost historical event.

Or it just helps to cement YouTube as the go-to place for uploading and sharing videos for almost any purpose which has a long-term positive effect for user engagement and retention
