Fair enough that I did not mention any timeline. And could’ve been general with “VCS”. And you are absolutely correct, that basics of some of these tools can be learnt in an afternoon.

In fact the industry i work in we don’t have git, but something similar to SVN (and proprietary, expensive and pathetic UI/UX)

Since, I am not in software industry, I won’t comment on whether such people might survive for more than 5 years without knowing about ‘VCS’.

However, I have slightly died inside when some Computer science students (graduate school, mind you) were using google drive with manually created timestamps as a backup strategy. The submission for this entire semester long actual project was on Github. as a final single commit uploaded a day before. (And no this wasn’t a squashed commit from a different repo.)

There might be a blurry line between people not sharpening their auxiliary tools vs never using or being slightly curious about them.

I am more of a glamour and bling on my tools person, and I don’t expect every engineer to derive the same pleasure that I derive just from tinkering with them; however, does make me wonder if there is a point when such an approach to not fully caring about simplifying your workflow (aka being lazy), might spill over into making poor engineering decision?
