GitHub is my copilot

Regarding using libraries as a better way to import third party code, that's casually true. But in my experience searching Stack Overflow for solutions many of the posts on Stack Overflow are about "how do I use <module> to do X? I tried the following code: Y". In other words, they're questions about how to use a library anyway, so it's not like their problem is that they're not using a library. Now of course someone could write a wrapper library which makes using the first library even easier, but someone would still ask questions on how to use the new library.

I've never gotten the problem with Stack Overflow copying/pasting to solve low-level questions of "how do I use this function" and "what does this error mean and how do I fix it?". Even changing the culture to have more bits of reusable code seems unlikely to help. If we create millions more Lego bricks, people will still ask how to use the bricks they chose to create their version of a Millennium Falcon.
