What is he up to? And how does he do it?

Two electrical engineers mapping Elon Musk’s companies as one engineering stack — nine domains, one map, a living development log. Not politics, not a fan site, not affiliated with Musk or his companies.

What's here

Why look — and why come back

It is one system

Cars, robots, energy, launch and neural are not separate news items. This site shows how those layers lean on each other.

The stack moves faster than the debate

Developments and Stats track engineering: facilities, output, releases. Not tweets, not valuation.

October is fieldwork; the atlas stays

The road trip is a temporary lens on the same stack. Journal fills in October; roadmaps, map and log keep running after.

Harry (The Hague) and Bernard de Groot (Deventer), both TU Delft electrical engineers. Scope: factories, labs, launch, the nine roadmaps. Not stores, Superchargers, or every Starlink gateway. Sources are public; unknown figures are marked “—” or “~”. About

Technology roadmaps

Nine engineering domains in three layers — reach, intelligence, ground. Expand a card for releases and end goals. Names link to the ecosystem, map, or development log.

Insights

Twelve engineering essays on the nine-domain stack — analysis, not a news feed. Four audio episodes sit above the reading.

Listen

Four episodes on how he thinks and what he is building.

The Musk Method How he thinks, asks, and runs 10 min

There is a meeting at SpaceX. An engineer presents a specification. Musk asks: who required this — name the person. Nobody knows. Delete it. That was not an outburst. That was a method.

This episode is not about who he is or what he believes politically. It is about how he thinks: first principles, the five-step algorithm, the idiot index, shortest-path communication, and why he automates last.

Not who he is. How he thinks — the method behind the map.

Musk and AI The man who fears it most and builds it fastest 12 min

There is a man who has called artificial intelligence the greatest existential threat to civilization — then built the largest AI supercomputer on Earth. He co-founded OpenAI, left, sued, and launched xAI in the same week he signed a letter calling for a pause.

This episode is the paradox: OpenAI, the pause letter, Colossus in Memphis, Neuralink, and the alignment problem. Not a simple story. A serious one.

The man who fears it most and builds it fastest.

Musk and the Machine Robots, factories, and the future of work 13 min

Most people who think about Elon Musk think about rockets or cars. People who have worked closely with him say something else: manufacturing. The factory. The machine that builds the machine.

This episode is gigacasting, the idiot index, Gigafactories as iterating software, and Optimus — the humanoid robot that is supposed to make work optional. The honest question is what happens to the humans in the middle.

The factory is the product.

Musk and the World Mars, Starlink, X, and population 10 min

In 2002 Musk flew to Russia to buy two old ICBMs, to send a greenhouse to Mars. The Russians didn't take him seriously. On the flight home he decided to build the rocket himself. SpaceX was born on that flight. The greenhouse is still the point.

This episode is Mars as backup, Starship, Starlink, X as the everything app, and the population decline he calls civilization's most underappreciated risk. The thread is redundancy. The tension is that so much of it runs through one person.

Backup for civilization — and who gets to build it.

The trip guide, then rabbit holes for the stops.

The Second Coming A road map through the Musk empire 13 min

In 2010, two brothers rode into Colorado on a Harley and came home with mountains in their memory. In 2026, they return — this time to trace the physical infrastructure of Elon Musk's companies across the American Southwest. Rockets, batteries, electric cars, tunnel systems, and a Dutch coffee chain in the Arizona desert.

This audio guide was made for Bernard and Harry de Groot. It follows their actual route, lenses their interests, and covers what you can actually see from a public road — which turns out to be quite a lot.

A personal audio guide for two brothers from the Netherlands on their second American road trip — this time through Elon Musk's physical empire.

Bruce Hornsby The piano man who refused to fit in 9 min

There is a song that reached number one in 1986, was played at civil rights rallies, and later sampled by Tupac — written by a Virginia pianist who spent five years being turned down by every label in Los Angeles. The song is “The Way It Is.” The man is Bruce Hornsby.

This episode follows the career that refused to stay in its lane: five years of rejection, a protest song dressed as pop, a hundred shows with the Grateful Dead, and a piano figure that keeps finding new moments to be relevant.

A rabbit hole for Ann Arbor — the concert that sets this trip in motion.

Techno Where the future was invented in a dying city 18 min

A young man in a dying Detroit sits with a cheap drum machine and makes something that sounds like machines dreaming. Derrick May, Juan Atkins and Kevin Saunderson — the Belleville Three — invented techno in the shadow of factory collapse, on instruments the industry had thrown away.

This episode is the story of that music: the city that made it, the machines that failed commercially and then changed the world, and the line from West Grand Boulevard to Berlin’s Tresor.

Belleville is forty minutes from where this trip begins.

Dutch Bros The brothers behind the coffee chain 9 min

1992, Grants Pass, Oregon. Two brothers have watched the family dairy farm collapse. They buy a second-hand espresso machine and a pushcart. That is where Dutch Bros begins.

This episode is Dane and Travis Boersma: the relationship business, the drive-through that treats ninety seconds as hospitality, Drink One for Dane, and why a Dutch coffee chain’s headquarters sits in the Arizona desert.

The photo stop this trip was made for — Tempe, Arizona.

Scalextric The slot in the track that swallowed Christmas 8 min

Christmas morning, Britain, sometime in the 1960s. A figure-of-eight in orange plastic, two cars, a controller like a pistol grip. Within an hour the carpet has disappeared. This is Scalextric.

From Fred Francis’s workshop in 1957 to Hornby, digital lane-changers, and the collector’s attic. The slot guides the car. Everything else follows from it.

For the afternoon at Electric Dreams, El Segundo — 606 Hawaii Street, next to LAX.

HiFi loudspeakers Bass without borders — the engineering of low frequencies 13 min

You push a woofer cone with your thumb. Somewhere past the linear travel, compliance goes non-linear, Bl falls, and what you wanted as bass arrives as distortion. After more than a century, accurate low-frequency reproduction is still not fully solved.

This episode is the engineering: Thiele–Small, large-signal nonlinearities, sealed versus reflex versus transmission line, cabinet radiation, and why there is no free variable.

An EE-level rabbit hole for the long stretches of American asphalt.
