This reminds me of advice I got from the VP of Eng at my first real full time tech job. This was back around late 1999 / early 2000. Peak of the dot com era.
He told me what most people think of as job security is totally wrong. If you're the only person who knows something, you become a liability. But if you're constantly teaching and sharing that knowledge you become incredibly valuable to the organization. That's when you have job security.
Since internalizing that advice, I always try to work myself out of job by ensuring I share anything I know. And I always pass this advice along to others. As you get more seniority in the organization, the way to have more impact and scale is to work through others by sharing your knowledge and helping them get better.
