I would argue it wasn't just the refrigeration, but also the suburbanization of living and the cost effectiveness of delivering the milk from the farm to the store, which (in theory) made milk cheaper. You would still need the milkmen if stores and supermarkets didn't exist. In an alternative world where we didn't invent commercial / household refrigerators, you could still buy milk from stores daily without the need of a milkmen, becaue ultra-pasteurization exists.
I guess thats the problem with analogies and I don't think either of us will get anywhere by further arguing about this one specific example.
Sorry, I made the comment about being on Fuck AI because of your edit to the original message. I wasn't trying to accuse you of anything.
Back to the AI stuff. I am sorry if I am a little sceptical about your claims about the "next generation of AI" and how "soon" they will outperform humans when even after all these years, money and energy poured into them, they still manage to fuck up a simple division question. Good luck making any model that needs to be trained on data perfect at this point, because AI slop that has been already generated and released in to the internet has already took care of that. Maybe we will have AGI at some point, but I will believe that when I actually see it.
Finally, I don't know about modern art being absurdly simplistic. How can you look at modern animation or music and call it absurdly simplistic. How can you look at thousands of game UI designs in Edd Coates' website and call them absurdly simplistic? All AI will ever create when it comes to art is some soulless amalgamation of what it has seen before, it will kill all creativity, originalty and personality from art, but businessman in suits will gladly let it take over human artists because it is cheaper then hiring human artists and designers.
