I remember in Canada, in 2001 right when americans were at war with the entire middle east and gas prices for the first time went over a dollar a litre. People kept saying that it was understandable that it affected gas prices because the supply chain got more expensive. It never went below a dollar since. Why would it? You got people to accept a higher price, you're just gonna walk that back when problems go away? Or would you maybe take the difference as profits? Since then it seems the industry has learned to have its supply exclusively in war zones, we're at 1.70$ now. Pipeline blows up in Russia? Hike. China snooping around Taiwan? Hike. US bombing Yemen? Hike. Israel committing genocide? Hike. ISIS? Hike.
There is no scenario where prices go down except to quell unrest. AI will not make anything cheaper.
