Growth usually means operating outside the confines of our previous experience to some extent. Tech careers are, hopefully, about growing - yes using new technologies, but also trying out new roles like management, architecture, sales, building a company... The more senior tech people get, the more they are doing outside the box they were initially hired in, until they are not doing that thing at all. As a result, everyone is doing some percentage of things they have little experience or training in, while they try to backfill that experience and training. Often there isn't someone better at it around either - that's why they ended up doing it in the first place. As soon as they actually get good at it they are pulled and pushed onto the next step. So, most people don't know what they are doing part of the time. I wouldn't want to label that imposter syndrome. We need to recognize our real limitations so we know what to learn and can control the risks.
