Folks- Generally when I buy a car, I don’t care about the tech. I am happy with Bluetooth streaming and maps on my phone. So, I hope to keep my cars for 8+ years. I just make sure I get reliable cars mechanically. But, given how everything in model 3 is driven out of a single console and the nature of software updates, how future proof is it? Future software updates might need better compute. My 2013 iPad still works, but barely. Is the compute/display unit replaceable? I replace my Mac/phone hardware every 3 years. Thanks.
