Hi-fi is already dead.
As for AI, I spent decades in software development and the last two years studying AI. The vast majority of people, including many software developers, don't understand the magnitude of how the world is about to change. If they start referencing what AI does now, or using historical timelines to predict its slow advancement, you know they don't understand AI from a technical perspective. AI's advancement is exponential, not linear.
In just a few years the vast majority of music will be generated. Musicians and studios will not be needed. The musical instrument market will massively shrink and along with it some interest in non-Pop music. As for higher-end home audio equipment, the market is too small to redevelop it with AI, so I doubt if it will change.
But that's small potatoes. Our whole economic structure is about to change, and therefore our whole societal structure. I think audio equipment will be the least of our concerns.
