On October 21st, 2026, Tesla told its investors that "Optimus production began in Fremont on our high-volume lines" (Tesla's results, page 6). Optimus is the humanoid robot Tesla first announced in August 2021, and the line is at its car factory in Fremont, California. A lot of people read that as robots now rolling off a production line, so I want to set out what Tesla actually said, and how we will treat news like it from now on.
What Tesla said
The written results say the robots coming off the Fremont line are "the first production-quality bots that we have manufactured". They give no number of robots built, no rate, no price and no customer (Tesla's results, pages 6 and 9).
On the call with investors the same afternoon, Elon Musk, Tesla's chief executive, called it "what I'd call early production". He said the line is built to make 20,000 robots a week, but reaching that "takes us probably at least a year, maybe a little longer", because parts of the design, especially the hands, are still changing. He said there is "still quite a lot of work to do with regard to the AI" before the robot is "truly useful for open-ended tasks", and that he expects to start delivering robots to companies outside Tesla "around the end of next year" (Tesla's recording of the call, from 9 minutes 43 seconds to 12 minutes 31 seconds). So production has started, as Tesla says. What has not started is robots arriving in numbers, or robots working for anyone outside Tesla.
Why robots belong to the economy part of the test
This site asks whether we are entering the singularity, the idea that machines will one day get smarter so quickly that the world changes faster than anyone can keep up with. It answers with a test in four parts. The fourth asks whether the world's economy has changed gear. The economist Robin Hanson found that each new era of history, from hunting to farming to industry, made the world's economy double about a hundred times faster than the era before. This part watches the World Bank's yearly figure for how much the world produces. In 2025 it grew 2.9 percent. The line the test is waiting for is 30 percent in a single year (the economy part).
I think robots matter here because most of the economy is still physical. Goods are made, moved, built and repaired, and almost all of that is done by people. AI that writes code and answers questions can only change the economy so much while that stays true. If the economy ever does change gear, machines doing physical work for pay is one of the likeliest ways it would happen, and the first signs would show up in counts of robots at work long before they show up in the world's output.
How we will treat it
The score does not change. The economy part is still scored on the World Bank's figure alone, and nothing a company says about robots moves it (the rules of the test).
Beside the score, I will now show measured evidence that machines are doing paid physical work. It goes in a table under the economy part, the way the AI-research part already shows figures that are not scored (the change, A33). Three kinds of figure go in that table, each marked for what it is:
- A count made by someone other than the robot's maker. That means a trade body's census, a government survey or a regulator's register. The International Federation of Robotics, for example, counted 542,000 factory robots installed around the world in 2024. It does not yet count humanoid robots on their own (its report for 2024).
- A customer's own published figures, such as hours of work or tasks done by robots in its operations, in an annual report or a filing.
- A maker's own count of robots built, shipped or working for paying customers. These are shown and marked as the company's word about itself. That is how we already treat Anthropic's figure that its AI wrote more than 80 percent of the code it added to its software: in the table, and not scored (the AI-research part).
Some things are not a measurement at all. A company saying production has begun, a target rate, a demonstration video and a forecast all fall in this group, so none of them goes in the table. Tesla's results of October 21st, 2026, are all of these, with no number in them, so today they add no row. When the person making a promise runs one of the companies we follow, a dated promise goes on the claims page instead, in their own words. That page records what the industry's leaders predict, not whether they turned out right.
The promises so far
Musk has put dates on Optimus several times, and the claims page keeps each one with what happened after.
- On August 19th, 2021, announcing the robot, he said Tesla would "probably have a prototype sometime next year". On September 30th, 2022, a prototype walked on stage (the prediction).
- On July 23rd, 2024, he said Tesla would ramp up production in 2026 and "at that point we'll be providing Optimus robots to uh, outside customers" (the prediction).
- On January 29th, 2025, he said several thousand robots would be built that year. On January 28th, 2026, he said Optimus was still "not in usage in our factories in a material way" (the prediction).
- On October 22nd, 2025, he said a third version of the robot would probably be unveiled in the first three months of 2026. In April 2026 he pushed the unveiling back towards the start of production (the prediction).
- On April 22nd, 2026, he said Optimus would probably "be useful outside of Tesla sometime next year". On October 21st, 2026, he put deliveries to outside companies "around the end of next year", which is the same year (the prediction).
- Also on October 21st, 2026, he said Tesla may release a video within "a month or two" of Optimus "doing things that um that are not pre-programmed" (the prediction).
So the date for robots working for outside customers has moved from 2026 to 2027 (the claims page).
What would move the number
The economy part moves only when the world's output grows faster. It grew 2.9 percent in 2025, and the line is 30 percent in a year (the economy part). Robots would push that figure only once enough of them are doing paid work to show up in what the whole world produces.
Before then, the table beside the score is where to look. Three things would fill it with real numbers. One is an outside count of humanoid robots working for paying customers, which no one publishes yet. Another is Tesla's first delivery to a company outside Tesla, with a count of how many robots went there. The last is a customer reporting what those robots actually did.
