I estimate there are 100 million people or more in China alone who work in sales and sourcing departments on manual supply chain processes that could easily be replaced with a single decent piece of open source software and a manager who can be assed typing in some figures or buying a smart factory upgrade to do it for him. That's very much tending towards post-work, for a significant chunk - 1/14th - of China, which is now I believe the world's largest economy. And that's the white collar scenario! And yet, by removing overheads and allocating resources to produce goods and services less wastefully for everyone, it will produce a net positive for the environment, despite the social upheaval. Then there's other areas at high risk from automation including transportation, QA/QC, law enforcement, financial and legal services, retail, manufacturing, construction, etc. I personally have no problem believing that at least 1/3 of society in developing or developed economies will see their lives change significantly through automation in the next 12 years.
