If the video is about an ongoing event, say the Titan submarine disaster, I'd rather watch videos posted last week them videos posted a year ago, because the new info makes the old content irrelevant.
If a search for videos about how to perform carbon fiber layups shows one with 1.2m views in the last year and another with 5k views from the past 6 years, I will probably watch the better performing video first.
But if I want to see a video about some esoteric subject like how the bathyscaphe triste worked, that isn't really changing much, I don't care about post date or view count.
Date is relevant information. I need it as part of my decision-making. Same as choosing between videos with 12 views and those with 10k views. It's not everything, but it's part of the equation. Let me fucking choose.
