Golden ages are usually defined in retrospect.

I was just thinking the other day that I wish someone had told me that "golden ages" are always coming and going. As an adolescent and young adult in the 90s, I thought that simply was how things were, and that they would continue to improve in the same way indefinitely.

I would say that we're in a golden age of AI, in that LLMs seem to be heavily subsidized. We're in a golden age of porn (sort-of-democratization via OnlyFans and similar), gambling (DraftKings), insider trading (PolyMarket), and private equity. We're probably at the end of the Golden age of social media influencers and crypto(scams), as most of the juice has been squeezed.

I think our recent golden ages have just kind of sucked compared to those of the past, by most people's subjective preferences and ethics.
