This is probably an unreasonably hard problem, but I asked ChatGPT to write me a boot sequence for an AWS machine that would write "hello, world" to the serial port then terminate the instance. What I got was some fairly generic stuff about bootloaders, and some hallucinated links to non-existent AWS Nitro whitepapers. I was probably expecting far too much, but it was disappointing given reports of it approximately solving problems out of whole cloth.
