Basically the title, you need to use the skills you have now and be a productive member of society.
I don’t mean go back and show the wheel or try invent germ theory etc.
For example I’m a mechanic i think I could go back to the late 1800s and still fix and repair engines and steam engines.
Maybe even take that knowledge further back and work on the first industrial machines in the late 1700s but that’s about it.
Yikes. I’ve moved from IT tech support to MGMT. I don’t really write with a pen, and largely rely on emails/teams. I think if we went back any further than the late 80s I’d be totally screwed.
