Picture this: you spent all day working on a file, saved it, closed it... and the next day you realize you overwrote the version that actually worked. Sound familiar?
We've all been there. Naming files with manual version numbers is chaos that spirals out of control fast.
Without history, there's no going back. The good code is gone forever.
On a team, nobody knows who changed what, when, or why.
Without traceability, finding the cause of a production bug turns into a full-blown investigation.
These problems are real and happen EVERY DAY on teams that don't use version control. It's not a matter of "if" it will happen, it's "when".
