A friend of mine who has at most written some SQL joins recently bought a cheap thermal printer on Amazon. The printer was meant to be used with a heavily ad and microstransaction laden app to operate over Bluetooth. He was able to use codex to hook it up to his MacBook and reverse engineer the printer then make a web service so he can print whatever he wants from anywhere.

I agree with you in that I now feel like a 100x engineer, but I think it would have taken me a long time to figure that one out pre AI.
