You only hurt yourself by drawing a line between academic knowledge and work knowledge. Very few people are actual geniuses that just retain information. Rather, most people know about things because they use them every day, that's all. Professors and researchers know CS stuff because that's what they need to get a paycheck. You know K8s because that gets you a paycheck. The fact that the former is called "knowledge" and the latter a "skillset" is just a technicality that shouldn't bother you. All knowledge is equal. If you need to know more CS stuff you will learn it no doubt!
