I think this will be very fascinating in 40 years time. It will be fascinating to look back on where I currently live, even if it is bulldozed and upgraded in the in the mean time.
It could be particularly fascinating to look back on your neighbourhood from when you were a child. I’m too old for that now, but I would love to Google street view my old neighbourhood. Everything would be just as I remember it as a child, which would be really nice to see. It’d be like looking through an old photo album, but one in which you could cruise around and see all the details you might like to go be nosey at.
