Be Aware of the Makefile Effect

I have an alternate theory: about 10% of developers can actually start something from scratch because they truly understand how things work (not that they always do it, but they could if needed). Another 40% can get the daily job done by copying and pasting code from local sources, Stack Overflow, GitHub, or an LLM—while kinda knowing what’s going on. That leaves 50% who don’t really know much beyond a few LeetCode puzzles and have no real grasp of what they’re copying and pasting.

Given that distribution, I’d guess that well over 50% of Makefiles are just random chunks of copied and pasted code that kinda work. If they’re lifted from something that already works, job done—next ticket.

I’m not blaming the tools themselves. Makefiles are well-known and not too verbose for smaller projects. They can be a bad choice for a 10,000-file monster—though I’ve seen some cleanly written Makefiles even for huge projects. Personally, it wouldn’t be my first choice. That said, I like Makefiles and have been using them on and off for at least 30 years.

Small nuance: I think people often don’t know because they don’t have the time to figure it out. There are only so many battles you can fight during a day. For example if I’m a C++ programmer working on a ticket, how many layers of the stack should I know? For example, should I know how the CPU registers are called? And what should an AI researcher working always in Jupyter know? I completely encourage anyone to learn as much about the tools and stack as possible, but there is only so much time.

That's why suggestions like RTFM! are stupid. I just don't have time to read every reference documentation of every tool I use.
