Their relationship is so interesting to me because it ties to the old "child" monarch vs his steely-eyed advisors. Long story short, its emotional manipulation to come at someone from a position of power and complain about "worry" and "losing sleep." In fiction and history we see these childish kings acting out with their advisors sort of calming them down as this stereotype of how wrong monarchy is, but instead its a valid and intentional leadership strategy: to emotionally manipulate your underlings by seeming hurt and needing of help. Gates played up this coddling attitude because it gets him the results he wants with minimum effort. Nathan recognized this signal and wrote out the logical part of the brain to counter Gates' emotional side. He coddled the child king. This is his job.
The C-levels in my life do this all the time. I've been manipulated many times like this. I think its linked to the habits of being a low-empathic personality. Its run of the mill manipulation which is what powers offices and sales all over the world. I imagine it gets results more often than not but its a bit pathetic looking and an acknowledgment human beings aren't logical animals, but primarily emotional and even the most hardened tech CEO is essentially playing emotional games with their staff, constantly. Its just so brazen and obvious when you see it like this. Especially when Gates is supposed to be the anti-Jobs, and this hard-nosed programmer not a diva, but surprise, surprise its diva behavior top to bottom in the C-suites, because diva-ism works.
I think the CEO playing as toddler has a ego stroking element to it and probably why this strategy is preferred over others. I tend to see C-levels in two groups, the alpha-male no-BS type and then the emotional manipulator type. I think both are ego pleasing (and probably both get similiar results), because the alpha gets the validation of his toughness and the manipulator gets the validation of his cleverness.
I think the latter is probably more pleasing for most personality types. You can still come off as the "nice guy" in polite company, even though you're being very demanding. Think how much warmer people like Sundar Pichai come off as compared to someone like Larry Ellison.
I also think there's a salesmanship aspect here. Its easier recruiting if you sell your company culture as a "nice" place led by a "nice" leadership. I think its a harder see to say "Look we're assholes here but the job and pay is good."
A wise leader surrounds themself with people they can truly trust in. In this message we see a glimpse into the dynamic between Bill Gates and Nathan Myhrvold, and my main takeaway is that Bill truly trusts Nathan here, enough to be vulnerable and speak openly about his worries.
While it's humorous and perhaps even enlightening to think of him as a "child king", I don't think he was only "seeming hurt" here or manipulating (unless you count all forms of emotional appeal as manipulation). Being honest and straight is a very effective way to lead those close to you.
It's also the leader's job to worry about threats like this and direct the attention of his advisors.
I'm just not seeing your pangloss-like explanation in the real world. Gates' words are very carefully crafted. He's not being vulnerable, he's being a leader and that means engaging in the Machiavellian action of manipulation and dishonesty to get the outcome he wants. Nathan knows he's being yelled at without being yelled at, its face-saving for both of them. This is saying "Why the fuck are you sleeping on Java, your future here depends on fixing the Java problem and telling me how you're going to do it," without saying that.
That's what I was trying to point out in my original comment. The "nice" and "hurt" leader is a common ploy and it gets results.
I see where you're coming from in the general case; I think it has been well established that leadership positions attract people well described by the dark triad. However, I don't agree that being a leader has to revolve around manipulation and dishonesty, and I've certainly seen this in the real world.
Even if Bill Gates has the dark triad traits I do not think they were on display in this particular email exchange. I truly don't think they were engaging in any "face-saving" here -- Nathan had been working for Microsoft for 10 years at this point, leading Microsoft Research and rising to the first ever Microsoft CTO. They coauthored a book called "The Road Ahead" in 1995. Bill has called him the greatest hire he made at Microsoft.
From every single source I've come across it seems clear that Bill Gates and Nathan Myhrvold are friends and share a deep mutual respect. No wonder they are still working together in 2021! You'd think after a lifetime of supposed abuse Nathan would have stopped working with him after becoming a billionaire, right?
