A comment before I read through fully but... I'm pretty skeptical about that chart.
What was the criteria, who made the numbers? Experts in each field?
Just using my own background experience, I find it highly unlikely that Education could be effectively automated any more than parenting could. I'd argue education is one of the more robust careers against automation.
Any teacher will know that being a teacher involves a ton of human connection, relationship building, social adaptation, things that are inherently impossible to automate. In many cases a teacher spends more time with students than their own parents, and within that contains a huge responsibility in partially raising those kids with the right values, virtues and strengths (While also not impeding on the diverse range of parents' views).
I mean, you could technically get all the paperwork BS organized and out the way perhaps a bit more efficiently, but I don't consider that element 'education'.
'Library' though, sure. We had an entirely automated one in a previous school like 8 years ago. Nothing new there.
