For programmers that were coding before good search engines: what did you do when you wanted to look up an error, etc back then? Crack open a tome for the language? Just curious as I can't imagine it was easy.
But software was in many ways simpler. The complexity was in squeezing out performance rather than piles of abstraction layers on top of one another. Knowing the hardware was more important and that was gleamed through trial and error.
The internet enabled the complexity that made software development dependent on it.
