According to the book "Abundance", everything gets devalued over time, meaning cheaper and easier to make, leading to some sort of utopia where everyone can afford more and more.
But the hard biological limit of 16 waking hours to consume all those things is unlikely to change anytime soon. With the cheapest yet best methods readily available to anyone, maybe the majority of what we will want to budget our attention spans on will be permanently crowded out by the AI-generated options.
I limit Internet browsing due to its addictiveness. I could have a similar rule for content created by computers.
I think the AI will produce more and better content than we ourselves, across the board. We will become consumers and observers of the AI content. The scientific and artistic life of the AI that we create will be more wonderful and beautiful by orders of magnitude than that which we can produce. We will be mere observers to the wondrous explosion, isolated islands of intelligence observing the great continents in awe. Some will merge with the intelligence, some will splinter and reject, most will observe. And the great filter will arrive, the gestalt being that our society becomes will bend apart the fabric of the universe and merge directly into a greater source. et sic transit gloria mundi.
Move on to the next scarce thing until we get to the point with true general AI and then we utopia away.
