Nvidia sells to OpenAI? OpenAI sells to...? If it's another company, there is always consumers (people) at the end of the chain. Remove that and then you remove other companies in the upper direction...
Your butcher sells to the blacksmith, the blacksmith sells to...? Are you implying that there are non-human consumers at the end of the chain?
I am implying exactly that. At the end of the chian there are always humans, so if AI takes all the jobs, who is going to pay for AI? Companies won't pay for AI because at the end of the chain no one is going to sell anything to anyone...
