You ever worked with someone who was really good at setting up environments? Or really good at refactoring the structure of the code? They'd always be pushing fixes and updates, and writing tutorials on the perfect environment set up, but when you look at their work, you realize they never actually shipped any products that required taking a risk or trying something unknown. All they did was restructure code that other people wrote.
These people are really good at having intellectually stimulating conversations. They're the kind of people who lurk on hobby forums and can tell you all about the hobby, but have never actually done it themselves. They're the people for whom the phrase, 'do you even lift' was coined. They'd lurk on /fit/ and talk about form and theory, but would never post any videos of themselves. They can tell you why you want to drive your hips out of the bottom of a squat, but they've never actually felt what it's like to be at the bottom of a squat and want to just give up and have to grind through it. They're the people who watch twitch streamers and think they're good at the game cause they understand the decisions the streamer was making, but they've never actually had to make those decisions themselves under pressure.
I've worked with a handful of these people over the years. They usually get in early and embed themselves in way that makes them seem important or very knowledgeable.
