Sometimes I go through the old screenshots and get nostalgic as the oldest are 10 years already.
I spend so much time of my life on my computer, so why not take photos of it?
Assuming 8 hours/day average of active screenshots every 5 minutes, would be (8*60)/5 = 96 shots per day. Times 3650 for ten years is 350,400. Divide by 60fps is 5840 seconds, by 60 is 98 minutes. So a decent movie length, as a single video.
Though, I imagine it'd be unfeasible to go through every screenshot and remove sensitive information.
(At a rough ballpark: if it took 20 seconds on average, to analyse and either bin or selectively-censor each screenshot, it'd take about a full working year, 8 hours per day.)
That’s pretty much the issue with privacy. A lot of feature feels invasive because the company don’t want to remove themselves from the operations. People don’t usually care because they either don’t understand the impact or they trust the government and the laws to reign in malpractice.
