If anything it’s the other way. The software updates provide a huge boost to the existing fleet, features that you would normally have to trade-in and get a new car to enjoy.

In some cases you can even upgrade the hardware (e.g. the AP and MCU) with the latest shipping parts to keep your model fresh. This is not universally true - there is some drama over a promised Model S MCU upgrade which a lot of people want only apparently only a handful of owners have gotten, but overall the approach is very refreshing.
