How is debasing someone's work a more effective way of motivating better future work than simply explaining clearly what you need improved?
Angry words are necessarily going to come across as personal no matter how much you want them to mean something else.
So, it depends on what your goals are. But, if you don't mind burning through staff and relationships, getting pissed will probably get you more short-term bang for your buck than being kind and calm.
And also, what if letting someone unleash on you is not a sign of strength, but simply sign of being weaker not being stand up for yourself
And also, what if someone need to be yelled at to do good work does not make him good engineer, really.
And also, what if long term crunch is ineffective and short term overtime should not require yelling.
What if it is possible to build large company while not being perfect and it is the "not perfect" thing about job.
That's possible, but I think "Jobs got angry because he angered easily, regardless of whether it was necessary to motivate people" would be the more parsimonious explanation.
Humans are actually perfectly capable of dealing with natural human-to-human interactions that aren't programmed by arbiters of empathy. This is because the species was the product of evolution, if not intelligently designed.
