I wouldn’t call of that nonsense but it is true that the learning curve is steep. The reward is worth it tho!
If you look back at 10–15 years ago, it was pretty much the same for developers: the very first version of git is 12 year old, using a version control system wasn’t common.
That’s a really good question.
Kactus and Abstract both have the same end goal: bringing version control to designers. The way is not the same tho, while Abstract “reinvents” GitHub and hides the underlying git repo, Kactus chooses to be really open about what is happening and gives you access to the repo.
