Vibe coding in the 90s was probably like learning C and pointers for the first time and then deciphering strange errors when you couldn't figure out how scanf worked, so you added asterisks and ampersands to the code until it compiled.
I once spent a couple hours debugging a perl cgi script. Nothing worked. Called in my colleague. Looks fine. We both were tearing our hair out. Sent it to the line printer, ordered pizza, and one of us read the code while the other typed it in. Couple hours later we finished and it worked.
