Well, nobody currently lives or will live in an earlier year, and it only gets less relevant as time goes on.

Huh? Are others time travellers?

Technologically, it can be cheaper to live a couple years back. Look at all these first gen iPhone SE's for about $100.

That’s what I do with everything possible. Tech becomes quite cheap, and if something breaks (which it does less often than with new stuff), there is no getting upset when the company refuses to honor the warranty, because there is no warranty. Just buy another one.

Absolutely! For instance, Jacob Rees-Mogg lives in roughly 1840 CE.
