Terrible article. I only skimmed it, but the gist seems to be that friendly, ambitious developers are likely to be “fake”. Worse, the article begins with the notion that a non-developer can distinguish good devs from bad devs without ever looking at their code.

No. If you’re not a programmer, your ability to evaluate the skill level of programmers is and will always be nonexistent. Your best bet is to ask senior devs who have proven themselves to evaluate their teammates. Technical people do not need more nontechnical people ruining things by pretending to have competencies that they very much do not have.
