When I started my voyage into Telsa I was excited for the software updates, because it meant I wasn't buying a car frozen in time. But in part of the Enhanced AP announcement was the tidbit that the new control unit has "40x the processing power", and in September Elon Musk admitted to “almost reaching the limit of the hardware” (source). It isn't clear to me if Musk's quote refers to computational power or the AP hardware. But still - are we going to find ourselves like iPhone owners, where software updates are technically available for download, but will bog down and become laggy since we're on outdated hardware? I don't know anyone with an 8 year old desktop computer or smartphone, is Tesla really going to be able to achieve the 8 year promise?
