Every empire in history has required humans to function. In an AGI future, that will no longer be true. The decisions made over the next decade will determine what that means for us as a species.

I haven't heard a single person that runs a business say 'AI is great because now my existing employees can produce 10x more'. I have heard a lot of them say 'AI is great, soon I will be able to fire most of my staff and replace them with AI agents I control myself.' You have to understand that hiring employees is a necessary evil for business owners, they don't do it out of the good of their hearts. They would much rather work with their core crew of 5 killers, each wrangling infinite superintelligent agents, than deal with Greg from marketing's 15th sick day of the year or Sally from HR's complaint about not enough workplace diversity. For all of economic history increasing production has required increasing human labour. Even over the past few decades, technology has acted as a partial substitute but not a full substitute. AI breaks this link between production and human labour, meaning GDP can rise without an increase in employment required.
