Do you know what happened to manufacturing when automation low-cost outsourcing happened?
It was wiped out.
It was devastating for certain sectors of the economy, even as 'net productivity rose' - the surpluses were acquired by some, not others.
A lot of 'ghettos' in the US are a direct result of mass factory closures.
Now - imagine that happening over the developing world, or rather, factories that were supposed to open, never did.
The developing world are 'services export' economy, with things like call centres etc. - and AI will more likely than not just evaporate those roles.
That those people will have 'access to ChatGPT' is besides the point when most of them don't even have computers (just mobile phones), or any way to apply that knowledge.
It's a bit like saying: 'The developing world has access to Wikipedia and all of Harvard courses online! They should all have great jobs!'
Unfortunately that's not how it works.
AI is going to help white collar workers, not pink or blue collar work which is low-skilled.
