I have no idea if "terrible developers whining on Medium" is a thing. What I am actually worried about are arrogant developers. They tend to cause the most damage, write the most "clever" code, have the worst communications skills, and will be the first to leave the team in the lurch and panic when shit hits the fan. There may of course be arrogant developers who can walk the talk, but I'm taking from personal experience. The ones with "Imposter Syndrome" - i.e. those who have a fear they're not quite good enough for the job - are more likely, again based on personal experience, to double check everything, to ask questions (from the rest of the team or Google), to write tests and test manually. They write "dumb" code that works and is well-commented and is as simple as possible. They have a desire to learn.
