IANAE (economist), However I see this large deployment of AI and manufacturer reducing cost of everything. These are businesses and need to make money. Once an entire supply chain is managed by AI from mining ores to having a end product say a phone, no labour and unions to deal with, you are left with cost of maintaining such machines. So instead of selling $200 iphone for $2000, and again, that $200 components may drop to few cents and the iPhone ends up costing $20 to manufacture. Then Businesses will be forced to sell these iPhones for $200 or maybe even less.
We have seen with other automation that costs drop, ice is cheap because there is no human delivering it to your door anymore.
So I see no money to be made in products as populace has no money and cost of manufacturing went from $100s to few cents.
Humans will be more free to enjoy their life. Who is to say some philanthropist won't set up auto manufacturing that gives free cars to everyone.
