Tell them how to make gunpowder.

That right here is all you need. If you can actually forge a gun and show them how to make gunpowder, you don’t need anything else. Although even then you would probably be executed shortly after for being a threat to the nobility.

Let me cook you something AMAZING!

First I need some curry…uh…okay, do you have salt? WHAT?

Alright, where is the oven? Time to prepare you some amazing lasagna! Where do you keep your noodles? No noodles? I guess I can hack it with potatoes.

…PO-TA-TOES! YOU…WHAT???

Okay nevermind, let me show you why you need to stop spending all your money on survival in warfare and instead fund my school! I can teach you to…uh…tell you about things we have in the future. No, I don’t know how to create any of that. But trust me bro, just give me money. No need to tie me to your trebuchet like that, I’m sure I can remember how to build an airplane somehowAHHHHHHHHHH

You tried.

Edit: But don’t worry, your myriads of novel diseases in your body will pretty much wipe out the continent you spawned on. Revenge!

So our technological progress has brutally outgrown our cultural one. I think you’re right.
