I like to see how phones resist the passage of time to understand how Apple updates and selects the phones that will not receive a new iOS update, so you guys think an iPhone 13 is future proof like an iPhone 14 or they will be discontinued at the same time?

Knowing the X model is no longer updating to new iOS versions, in 2024 we should see the XR, XS and maybe, MAYBE, the 11 losing support to newer updates.
