20 years ago, I was using Visual Source Safe. The amount of time lost to corruptions from internal VSS bugs, deleting files forever, SMB issues (one of them being people editing files off it directly), its abysmal branching and pinning strategies, truly awful performance, etc[0]. was considerable. We tried TFS as soon as that was available, got rid of it in less than a week in favor of SVN. That was a considerable improvement until about 2010 when we got sick of constant merge headaches and poor performance and awkwardness trying to jump between branches. People slam on git a lot, but the number of incidents resulting in lost work or bad merges went from fairly routine to maybe a scant handful in the past 14 years, most of which could have been avoided by protecting mainline branches and tags from junior devs or just following good source control daily routines.
