This is a fair point... but also just what happens with technology and time.

I assume you junked the radio not because it was broken (that can happen to any gear) but because the 30-pin interface itself is no longer desired -- it's no longer the best way to get the content you want (ie: from your phone).

This isn't really a different situation from a 20-year-old car (CD player), 35-year-old car (cassette deck) or 50-year-old car (8-track).

20 years from now, if there's a market for it and it's technically possible, someone will make adapters to get AA/Carplay units to be compatible with whatever the current technology is -- basically the 2043 equivalent of a cassette adapter.
