Sure, but not for the reasons the (really light) blogpost suggests. It's not about seniority in a specific technology or in sitting at a particular desk for enough years. It's about judgement and experience. Yes, some people never acquire these things, and some people have an unusually large amount of it from the get-go. But when you've been in the trenches for a decade, you (tend to) simply know things a junior doesn't. You know where you spend your efforts, and which red herrings to avoid. You know how to navigate the systems, the politics. How to interface with colleagues. And so on.
