Uh, this couldn't be more false. I've implemented these from scratch at my company and rolled them out org-wide and I've yet to watch a youtube video and don't consume any influencers. Mostly by just using the tools and reading documentation - as any other technical tool.

Perhaps your blanket statement could be wrong, and I would encourage you to let your mind be a bit more open. The landscape here is not what it was 6 months ago. This is an undeniable fact that people are going to have to come to terms with pretty soon. I did not want to be in this spot, I was forced to out of necessity, because the stuff does work.
