There are two types of people.
Those who can extrapolate from incomplete information.
Yes, there are many who hold positions with atrophied skills. They tend to be managers and executives, however. Most engineers, including those on my team, want to drive their knowledge and skills.
Those who don’t? Consider the CTO who proclaimed years ago that we should move all storage to object. Guess they met a vendor or saw a PowerPoint slide. It didn’t matter that NAS and SAN are critical platforms. Didn’t matter that object lacks functionality. Or even that we wrote our own NAS API.
Technical people told him that the objective of moving to all object was flawed. He got rid of most of them. They were right of course, and they’d kept their skills up. We would soften the all object storage message years later. We took outages because of the distraction and bullying.
I watched good people get shown the door or made miserable. God how I wished I’d be shown the door. I’m one sabbatical away from my resignation.
But don’t proclaim that keeping one’s skills makes them safe or that those who don’t lose their positions. That’s just plain wrong.
