completely true but at that point you've been in the industry for a few years and already know how to code. hopefully you'll have spent some of that free time catching up on the social skill if you minmaxed on knowledge acquisition in university.
personally I completely understand the idea of a lone wolf coder. I'm self taught and started aggressively learning web development while working a dead end job. At some point I realized if I hung out with my coworkers and smoked weed/drank after hours with them like everyone else was doing, this is what Id be doing for the rest of my life. You're the average of the people you hang out with. if the average is hell bent on mediocrity and thats not what you want, isolation is just what you have to do till you are good enough to find a new crew.
As also stated by you that it doesn't take long to reach there. Average software engineers could reach there within 5-7 years. Assuming that a person only started taking cs in university and started working after graduation, that still puts him at this level below 30s. That's not counting the ppl who started programming young, or the ppl who learn faster than average, or the ppl didn't graduate and went straight to work, etc.
My point is that OP's points really only applies to the ppl who are new to the job. Inter-person skills comes into the play in just a few years.
