This is pretty dangerous. Another poster mentioned Yahoo pre-Mayers. Generally, positions like what you describe are either politically protected: a manager with a large number of reports has more "importance" than a manager with few, so some managers try to inflate their staff, or, the position has just slipped through the cracks as times change around it.
The problem comes when you've been in that position for 10 years, doing little to no significant work, not building or honing any skills, and suddenly a new management comes in and cleans house, and you're gone. Now what?
I work for the government and we have a lot of folks like what you describe, but with less income. As long as they show up for work and answer a few emails, mostly, they can get by. This works, I guess, if you're just a few years from retiring. But we do sometimes get aggressive politicians in office who promise to "cut the fat", and we have had cuts and layoffs in the past. So imagine yourself, at 25, you take a position and intentionally don't learn, don't advance, and just do the minimum to collect the salary.
10 years later, you're 35 and still working with Java 6 on some legacy system that needs 2 hours a week of maintenance. That's your whole job. Suddenly, some political upheaval happens and a bunch of folks, including you, are laid off.
Can you get back in the game? Of course. Would it be a lot easier to get back in if you took that time to keep your skills at least somewhat up to date?
That said, I'm very sympathetic. I'm a computer programmer because I've always been good at it. When I was a kid, and in high school, and so on. That's the only skill I learned. But I don't like computers. New frameworks don't excite me, they make me feel tired. When I go home, I don't want to play with the newest technology or even gadget. I dream of getting out of computing all together, but, nothing else would bring the salary combined with the light workload. It's a "bronze handcuffs" situation (I say bronze, because, as a government worker, my salary is too low to qualify for anything else). I had a job for a while teaching remedial basic math to adults, which was pretty neat, but it was part-time, no-benefits, low wage. That's the kind of thing that is fulfilling, but doesn't pay the mortgage.
Even so, I read HN. I sometimes do make time to try new ideas, even small ones. I'm not using node.js or angular, but, at least I've heard of them and know what they are. Don't become the guy that hasn't heard of them [where them refers to whatever is fresh] and doesn't know what they are... Or I worry you'll find yourself in a very difficult spot in a few years.
