Git isn't even 20 years old. I graduated before that. I learnt the basics of version control in a day and searched to unblock myself when needed without fuss. It's not a particularly big deal.
When i read things like this I'm extremely concerned and embarrassed for the people demanding new graduates be rote taught specific tech stacks. That's the real concern here. The projection from having so little faith in their own ability to learn they can't even see that something like git is going to be one of the many things needing to be learnt on a new job.
