I think our memories are rooted in time and space. "Which years did we go on our family holiday to Scotland? Can I see all my videos from when my kids were toddlers? Let's see that specific photo of sunset at the Grand Canyon, I think around 2021? What was the cafe we stopped at on our road trip? How did my flower garden change since I bought my house?"

(I put in a timeline (histogram) of photos, and keyword search, to serve these kinds of needs.)
