It's not that being introverted is bad. It's totally fine. But sometimes introverted people end up not getting what they want because they don't get noticed. That's not intrinsically bad, but it can be frustrating at times if you aren't getting the opportunities that you would like to have.

Look at some well-known popular tech personas that have done well for themselves. Many of them seem to know approximately nothing, technically. I roll my eyes when I see them linked to as some all-knowing sage. Yet they've now got tons of resources to do whatever they want. If they had thought "wow, I don't know shit and my skills are probably below average" they wouldn't have continued to pump out those "divisive clickbait" articles and be an "asshole" and subsequently land all sorts of lucrative contracts.
