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.
Gonna blow Galileo’s mind with an equatorial telescope mount. Even more so when I attach a clock to it and make it automatically track the sky. I’m skilled enough to construct one, assuming I can communicate with other laborers to have the parts made
As far as general labor skills go though, I could make a living just about any time with agriculture. Unskilled labor is timeless
Per the OP’s post:
This is true, but I don’t like deleting comments because everyone can see that I left one and deleted it, and I get self-conscious about that
So instead of deleting the comment I just added on some bullshit about unskilled labor
