At the Wall Street Journal’s (WSJ) CEO Council Summit, Elon Musk shared some updates on the Tesla Bot and how it could alleviate human labor shortage in the future.
During Tesla AI Day, when the company unveiled the Tesla Bot, Musk explained that the humanoid robot could be used to help with “boring, repetitive, dangerous work.” At the WSJ summit, Musk elaborated further on the primary purpose of the Tesla Bot.
“[The Tesla Bot] has the potential to be a generalized substitute for human labor over time. The foundation of the economy is labor. Capital equipment is essentially distilled labor… The fundamental constraint is labor. There are not enough people. I can’t emphasize this enough. There are not enough people. I think one of the biggest risks for civilizations is the low birthrate and the rapidly declining birthrate.
“And yet, so many people, including smart people, think there are too many people in the world and think that the population is going out of control. It’s completely the opposite. Please look at the numbers. If people don’t have children, civilization is going to crumble. Mark my words,” Musk said.
Multiple studies through the years have shown that global birth rates are declining. According to the UN Population Division, for a country to naturally replace its population, it should have a fertility rate or replacement rate of at least 2.1. Very few countries have a birthrate that meets the minimum replacement rate.
A quick look at the map below reveals many countries worldwide have a fertility rate below 2.0. For instance, China has a fertility rate of 1.7, and Japan’s is 1.4. Asia’s fertility rates seem to fluctuate between 1.0 to above 2.1.

Meanwhile, in Europe, most nations have a fertility rate below 2.1. For example, Germany has a fertility rate of 1.6, and Italy’s replacement rate is 1.3. In North America, it is below 2.1 as well. The United States has a fertility rate of 1.7, and Canada’s replacement rate is 1.5.
Some parts of the globe have fertility rates higher than 2.1, like Nigeria, which has a replacement rate of 5.4. However, births are trending on a decline. For instance, Nigeria’s current fertility rate decreased from 6.35 in the ’60s to its current rate in 2019.
Experts believe declining birth rates could slow economic growth. One study published by the University of Alabama identified some adverse outcomes of declining birth rates, including labor shortages, wage pressures, and large turnover rates. The Tesla Bot seems to be a resolution to expected labor shortages caused by low birth rates.
Tesla is due to release a prototype of its humanoid AI robot next year. The company has already started a hiring ramp for the Tesla Bot in 2022. Tesla has posted jobs mostly related to manufacturing and engineering for its humanoid robot, like postings for Controls Engineers and Engineering Technicians.
Musk shared also shared some details about Tesla’s progress with its humanoid AI robot project at the summit.
“With Tesla Autopilot and Full Self-Driving we’re effectively creating the most advanced, practical AI for navigating the world. You can almost think of Tesla as the world’s biggest company, or semi-sentient robot company. The car is already kind of like a robot on four wheels. So then, it’ll probably take the same technology and put it in a humanoid robot and make it be useful.
“Essentially, for the humanoid part, we need to develop some custom actuators and sensors and essentially use the Tesla Full Self-Driving or Autopilot or just generally speaking, real world navigation AI for the humanoid robot and I think this could be quite profound. I don’t know exactly when we will get this right, but we will get it right,” he said.

Tesla Cybertruck engineer reveals new changes in ‘constantly evolving’ pickup
Tesla Cybertruck Lead Engineer Wes Morrill revealed the company has made several changes to the all-electric pickup, which he calls a “living thing, constantly evolving and improving.”
Cybertruck is manufactured at Tesla’s Gigafactory Texas just outside of Austin, and over the past few years, Tesla has continued to make small changes to the pickup to improve everything from cost, reliability, serviceablility, and manufacturability.
“The finish line isn’t getting to production. A product is a living thing, constantly evolving and improving,” Morrill added.

Some of those changes are yet to be revealed, but perhaps the most notable one was the change Tesla made to the aero shield that sits underneath the truck. In the past, it was aluminum, but now the Cybertruck is using a self-reinforcing polypropylene.
Morrill said that the polypropylene is “stretched into fibers and then laminated into the form,” and is much more durable, much lighter, and significantly cheaper than aluminum when it is manufactured this way.
It also enabled some improvements in the geometry of the Cybertruck, improving the manufacturing around the bolts and edges, in addition to minor form changes. These all benefitted the Cybertruck in more ways than one: specifically with durability and improved drag.
I was surprised by how interested people were to find out we made a relatively benign change to the Cybertruck aero shield, a part of the car most people never even see. So I’ll share some more details.

Typically, Teslas are not necessarily identified by model year because these changes are fluid and occur when the company sees fit to implement them. It is not like other automotive companies, which usually make sweeping manufacturing changes when building a new model year.
Instead, Teslas are recognized by their “generation” or “era.” For example, those with a newer Model Y might refer to their car as a “Juniper.” This is the same with Model 3, as many refer to the new body style as the “Highland.”
Tesla’s manufacturing changes are proof of the company’s constant need to improve its products and move things forward with its vehicles. There is no need to drag one’s feet and wait until next year if the product can be made better right now, and that’s precisely what Tesla did with the Cybertruck.

Tesla Cybercabs narrowly miss deadly Amazon cargo plane crash
An Amazon cargo plane crash near Miami’s airport stopped feet from dozens of Tesla Cybercabs.
An Amazon Prime Air Boeing 767 cargo jet overran the runway at Miami International Airport on Sunday afternoon, killing five people and injuring five more. The jet, operated by North Carolina based carrier 21 Air as Flight 7598, touched down around 2 p.m. after arriving from San Juan, Puerto Rico, then crossed the airport perimeter, plowed across NW 67th Avenue and struck multiple vehicles before catching fire, according to the Associated Press.
Photos and video from the scene show the aircraft’s nose stopped within meters of a fenced staging lot holding dozens of gold painted Tesla Cybercabs, the steering wheel free robotaxi Tesla began putting on public roads in Austin last week. Miami-Dade Fire Rescue has confirmed the plane struck “multiple vehicles” but has not said whether any Cybercabs were among them, and neither Tesla nor airport officials have addressed the fleet directly.
The Cybercabs had not yet entered commercial service in Miami. Tesla’s existing Robotaxi operation there runs on modified Model Y vehicles and has been unsupervised since Ashok Elluswamy confirmed the detail on X in July.

Elon Musk offered the briefest of reactions. Replying to a Zero Hedge post about the Cybercabs sitting so close to the wreckage, he wrote a single word: “Weird.” He has not commented further, and Tesla has not issued a statement.
The timing puts Tesla’s newest vehicle near an unrelated but highly visible tragedy just days after its Austin debut, a launch that had already drawn scrutiny from federal regulators. The National Highway Traffic Safety Administration opened an audit how Tesla certified the Cybercab as compliant with federal vehicle safety standards, a process Teslarati covered after the vehicle’s September 3 launch event. That inquiry concerns the car’s lack of a steering wheel and pedals, not the Miami crash.
Investigators from the FAA and NTSB are focused on the plane, not the parking lot beside it. Flight data reviewed by outlets including Simple Flying show the 767 touched down around 170 knots, well above the 135 to 140 knot range typical for the aircraft, though investigators have not determined a cause. Amazon said it is working with authorities and that its priority is the safety of everyone affected.
Whether any Cybercabs were damaged, and what Tesla plans for the fleet parked near one of the country’s busiest airports, remain open questions.

Tesla crosses major Unsupervised Self-Driving milestone
Tesla has reached a notable benchmark in its autonomous driving program after its Robotaxi fleet surpassed one million miles of unsupervised operation. The company made the announcement during its Cybercab event in Austin on September 3.
Tesla Vice President of AI Ashok Elluswamy told attendees he was happy to report the fleet had achieved one million miles of unsupervised Robotaxi operation as a testament to safety.
The new total marked a sharp increase from the 380,000 unsupervised miles Tesla disclosed during its second-quarter 2026 earnings update in late July.
In roughly six weeks, the company added about 620,000 miles. That acceleration followed Tesla’s decision to remove in-vehicle safety monitors from most of its operations outside the San Francisco Bay Area.

Tesla first launched Robotaxi service in Austin in June 2025 with safety drivers present. It later began fully unsupervised rides and expanded into Dallas, Houston, Miami, Orlando, and Tampa. The San Francisco Bay Area remains the exception, where a safety monitor still rides in the vehicle under California permitting rules.
The company has not released a city-by-city breakdown of the one million unsupervised miles.
The milestone arrived as Tesla began offering public Cybercab rides in Austin. The purpose-built vehicle has no steering wheel or pedals and is designed only for autonomous ride-hailing. Production versions joined the existing fleet of modified Tesla vehicles already operating in the service.
Tesla’s unsupervised mileage is growing at a double-digit weekly rate according to earlier company comments, yet its fleet size remains modest compared with established competitors. Waymo has accumulated more than 200 million fully autonomous rider-only miles. Tesla has described its own unsupervised operations as having recorded zero notable incidents in the period leading up to the July update.
The one-million-mile figure reflects Tesla’s shift from supervised testing to broader driverless service in multiple states. It also highlights the company’s strategy of using both existing Model Y vehicles and the new Cybercab to scale its network.

Whether the rapid recent growth continues will depend on further city expansions, regulatory approvals, and the performance of the purpose-built Cybercab in everyday paid rides. Tesla has not specified how many of the latest miles involved the new vehicle versus the rest of the fleet.
The announcement underscores Tesla’s progress toward a larger robotaxi network while illustrating the remaining gap in total autonomous experience relative to longer-operating rivals.
