Home Audio, in terms of speakers and amplifiers, was "solved" in the 1980's and 1990's. A lot of this equipment will last for decades, is serviceable, and isn't dependent on the cloud.
Hell, even enclosed devices like the iPhone still last for almost a decade. I know, I had multiples ones in use for that long. So not being able to be serviced easily probably causes fewer problems than you’d think if people held on to devices for their maximum lifespan.
