WEEKEND RECAP · SEPTEMBER 27, 2026
The week AI got closer and the stack got taller.
Grok 4.7 landed and went straight into real Tesla engineering work. Starship finished its dress rehearsal for the first planned orbital flight. Semi production scaled. The multiplanetary stack tightened in five days.

ACROSS THE EMPIRE — WEEK IN REVIEW
|
Grok 4.7 became a daily tool
The model arrived mid-week. Independent coding evals put it near the top while costing far less. Tesla engineers reported shipping real FSD and Cybercab features with overnight agents built on it. Then the same model moved into the car as Grok Bot — managing inbox, calendar, and tasks hands-free.
Why this matters: Performance plus price turns a frontier model into infrastructure. Putting it inside the vehicle makes the car a workplace, not just a ride.
|
|
The orbital attempt is days away
Ship 41 reached the pad. The full stack was completed. SpaceX ran full-stack tests and finished the launch rehearsal. Elon called the vehicle magnificent and confirmed preparation for Monday. Flight 14 is still the first planned orbital Starship mission and the first to deploy operational Starlink V3 satellites.
Why this matters: Stack complete plus dress rehearsal complete is the strongest public signal yet that the first orbital attempt is imminent.
|
|
Semi production scaled
Tesla’s first factory built specifically for the Semi is now running high-volume production. Design capacity is 50,000 units per year across 1.8 million square feet. Early customers are already receiving trucks.
Why this matters: Volume is the only way electric freight becomes cost-competitive at scale. The dedicated plant is the concrete step.
|
|
Elon shortened the AI horizon again
Responding to a long-standing forecast that most scientific fields would become branches of computer science in 10–20 years, Elon called the timeline conservative. His version: AI will beat all fields by the end of next year or 2028 at the latest.
Why this matters: Compressed timelines change how companies, regulators, and individuals plan. The gap between today’s models and that claim is the central tension of the next two years.
|
|
The stack is becoming multi-layered
In the same week Google announced it would fly TPUs on a SpaceX mission to test compute in orbit. Crew-13 Dragon moved to the pad. Starlink continued expanding into new countries and use cases. The physical and digital layers of the multiplanetary stack advanced together.
Why this matters: Rockets, models, trucks, and orbital compute are no longer separate stories. They are parts of the same system being built in parallel.

THE MAIN EVENT
|
THE STACK TIGHTENS
A better model, a ready rocket, and a scaled truck all arrived in the same five days.
I spent the week watching three systems move at once. Grok 4.7 did not just post strong eval numbers. It went into overnight engineering agents at Tesla and then into the car itself as a hands-free work tool. The model became useful the same week it launched.
At Starbase the physical stack kept rising. Ship on pad. Full stack. Dress rehearsal complete. Monday remains the target for the first planned orbital flight. Elon looked at the stainless steel and called it magnificent.
Meanwhile the Semi factory that was built for volume finally started running volume. Fifty thousand units a year of capacity is no longer a slide. It is a plant with trucks leaving for real fleets.
Elon also pulled the AI timeline tighter again — all fields by the end of next year or 2028. The same week Google decided to test TPUs in orbit on a SpaceX ride. The digital and physical layers are no longer separate projects.
My take: The multiplanetary stack is the combination of energy, transport, compute, and intelligence. This week each piece advanced. The next test is whether Monday’s orbital attempt and the Semi’s volume ramp both hold.

ELON ON X — WEEK’S QUOTES
|
TIMELINE
“Your prediction was conservative. AI will beat all fields by the end of next year or maybe 2028, at the latest.”
The compressed horizon that framed the week’s AI discussion.
|
|
STARSHIP
“Starship is magnificent”
After the vehicle completed its launch rehearsal.
|
|
SCALE
“An Earth economy is less than a trillionth the size of a K2 economy”
The long-term frame that sits behind Starship, energy, and multiplanetary goals.
|
THE TROLL REPORT
|
🧌 “Grok is still behind the biggest models.”
Near the top at a fraction of the cost is a different kind of win. Daily workhorses are chosen for value, not just the final leaderboard point.
|
|
🧌 “Another compressed AI timeline that will slip.”
Musk has been consistent about pulling dates forward as the models improve. Whether 2027 or 2028 lands exactly, the direction is clear and the gap is closing.
|
|
“Your prediction was conservative. AI will beat all fields by the end of next year or maybe 2028, at the latest.”
— Elon Musk, September 22, 2026

|
The model is useful. The rocket is ready. The stack is tighter.
Forward this to the person still treating the multiplanetary future as distant.
