What You Can't First-Principle

I've been on a small jag of books about first-principles thinking. Unscripted. The Book of Elon. Both make the same case from different angles. Reduce the problem to physics, ignore the convention, build it cheaper, ship it faster. It's an addictive way to think. It also has a quiet boundary I keep forgetting.

You can't first-principle human bonds.

The optimizer mindset works on rockets because a rocket has no preference about being optimized. You can shave mass off it, simplify it, accelerate the build cycle, and the rocket will sit there and let you. Cost goes down. Rocket gets to orbit. That's the whole transaction.

People are not like that. There is no equivalent of "delete the part" in a friendship. The hour you spend listening to your mother repeat a story she told last Eid is not waste to be removed from the schedule. The slow lunch with the friend who is going through something is not a candidate for the Algorithm. The frictions in a long marriage are mostly the marriage.

The category error I keep almost making is importing engineering language into rooms that don't speak it. I've caught myself wondering what the ROI is on a particular relationship, doing opportunity-cost math on whether a wedding is worth the flight, or once comparing my dad against an imaginary better one. Every time I do, I'm worse to be around for about a week, and also wrong on the merits.

The metric for any of it doesn't exist. There's no "cost per ton to orbit" for being a son. The success function for being a friend isn't even well-defined, and the harder you try to define it, the further you drift from what people actually need from you, which is approximately to show up, listen, remember, and not be doing math under the table.

The engineers I know who are good at this stuff usually have a separate person who quietly reminds them of it. A grandmother, a sibling, a wife who refuses to be a roadmap. The human bonds part of life runs on a different operating system. It optimizes for things you can only measure in retrospect, like trust and tenderness, and only by looking back twenty years.

The skill I want next to the first-principles one is the one that knows when to put the calculator down. Build the company on physics. Build the relationships on time.
