Obviously I agree. I suppose I got here because this industry often seems laser-focused on CTOs, 10x engineers, and individuals with a generally accepted as outstanding level of knowledge in some niche field or specialization. This guy has none of that, hence “mediocre” but I agree he’s anything but.
Yes, this person is an expert manager.
Even being able to have such a firm grasp on your emotions is hardly the stuff of mediocrity.
