One of Tesla’s engineers at the helm of the Dojo AI supercomputer program has announced his departure, coming as the latest shift in the company’s high-level management shifts in recent weeks.
In a post on LinkedIn on Saturday, Dojo Fabric Lead Eric Quinnell announced that he would be leaving Tesla, after just under four years since he first started with the company. Quinnell noted in the post that it is “with a heavy heart” that he says goodbye to the company, along with posting a funny mad libs-style “farewell email” that he says others are welcome to use too.

During his time at Tesla, the engineer worked both on the fabric for the Dojo supercomputer and on the Tesla Transport Protocol over Ethernet (TTPoE), which the company officially made open-source just a month ago.
Quinnell says he is leaving to work at Tranium after the four-year stint. He also had previous experience working at Samsung’s R&D Center in Austin for over six years, AMD for over six years, and the firm Arm for just over a year before coming to Tesla.
The news also comes as Tesla has recently made a few promotions, and as a few other high-level managers and executives have departed throughout this year.
Last week, Tesla promoted former Autopilot Direector Ashok Elluswamy to the role of VP of AI software. Just a day later, Tesla also promoted Milan Kovic to VP of the Optimus humanoid robot program, after being the Director of Autopilot Software Engineering, and it bumped Omead Afshar up to the position of Senior VP of Sales and Manufacturing.
Tesla has also faced a few other high-profile departures this year, most recently including that of VP of Finance and Business Operations Sreela Venkataratnam, who left in August after 11 years. In May, Tesla lost Giga Texas Manufacturing Director Renjue Zhu after five years.
Perhaps most notably, Tesla saw SVP of Powertrain and Energy Engineering Drew Baglino leave in April after 18 years, as followed by VP of Public Policy Rohan Patel, who left after eight years.

Tesla addresses door handle complaints with simple engineering fix
“We’ll have a really good solution for that. I’m not worried about it.”

Tesla is going to adjust one heavily scrutinized part of its vehicles after recent government agencies have launched probes into an issue stemming from complaints from owners.
Over the past few days, we have reported on the issues with Tesla’s door handle systems from both the Chinese and American governments.
In China, it dealt with the Model S, while the United States’ National Highway Traffic Safety Administration (NHTSA) reported nine complaints from owners experiencing issues with 2021 Model Ys, as some said they had trouble entering their car after the 12V battery was low on power.
Bloomberg, in an interview with Tesla Chief Designer Franz von Holzhausen, asked whether the company planned to adjust the door handle design to alleviate any concerns that regulatory agencies might have.
Regarding the interior latch concerns in the United States:
- Von Holzhausen said that, while a mechanical door release resolves this problem, Tesla plans to “combine the two” to help reduce stress in what he called “panic situations.”
- He also added that “it’s in the cars now…The idea of combining the electronic and the manual one together in one button, I think, makes a lot of sense.” Franz said the muscle memory of reaching for the same button will be advantageous for children and anyone who is in an emergency.
Regarding the exterior door handle concerns in China:
- Von Holzhausen said Tesla is reviewing the details of the regulation and confirmed, “We’ll have a really good solution for that. I’m not worried about it.”

The new Model Y already has emergency mechanical door release latches in the back, but combining them in future vehicles seems to be an ideal solution for other vehicles in Tesla’s lineup.
It will likely help Tesla avoid complaints from owners about not having an out in the event of a power outage or accident. It is a small engineering change that could be extremely valuable for future instances.

Elon Musk calls out viral claim of 10,000 Tesla Optimus deal: “Fake”
For now at least, Tesla seems determined to focus on the development of Optimus V3.

Elon Musk has provided some clarification to recent reports suggesting that PharmAGRI, a US pharmaceutical and agricultural infrastructure company, is looking to deploy 10,000 Optimus robots for its operations.
Musk posted his clarification on social media platform X.
Alleged Optimus purchase
Recently, reports emerged stating that PharmAGRI Capital Partners will be tapping into Tesla’s humanoid robots for its operations. The firm claimed that it had executed a Letter of Intent with Tesla to deploy up to 10,000 Optimus Gen 3+ humanoid robots across its SuperPharm and CEA facilities. This should allow the company to automate its labor and ensure diversion control.
A comment from Lynn Stockwell, Chairwoman & CEO, suggested that the company really was partnering with Tesla. “With Tesla robotics powering our facilities and DEA-licensed infrastructure in place, we can scale with precision, meet federal sourcing mandates, and deliver therapies that are compliant, secure, and American-made,” she said.
Elon Musk clariies
News of PharmAGRI’s Optimus claims quickly spread on social media, though some Tesla watchers argued that it seemed unlikely that the EV maker will commit two legions of Optimus robots to a rather unknown company this early. Some pointed out that Tesla typically commits to high-profile customers to test its early products, such as PepsiCo with the Tesla Semi.
Photos from PharmAGRI’s website depicting Tesla Optimus bots, as well as the rather basic look of the website itself, also brought more reservations to the company’s claims. Ultimately, Elon Musk weighed in on the matter, responding to a post about PharmAGRI’s Optimus-filled webpage. Musk was quick and direct, simply stating, “Fake.”
Elon Musk’s comments were quite unsurprising considering that Optimus is still very much in active development, and thus, it is quite unlikely that the company is already taking orders or even Letters of Intent from potential customers at this time. For now at least, Tesla seems determined to focus on the development of Optimus V3, which Musk has noted will be “sublime.”

Elon Musk: Self-sustaining city on Mars is plausible in 25-30 years
Musk noted that true self-sufficiency requires Mars to develop “all the ingredients of civilization.”

Elon Musk has stated that a self-sustaining human settlement on Mars could be established in 25-30 years, provided launch capacity increases dramatically in the coming decades.
Speaking at the All-In Summit, the SpaceX CEO said building a self-sufficient colony depends on exponential growth in “tonnage to Mars” with each launch window, highlighting Starship’s role as the company’s pathway to interplanetary initiatives.
Mars settlement goals
Musk noted that true self-sufficiency requires Mars to develop “all the ingredients of civilization,” from food production to microchip manufacturing. Starship Version 3 is expected to support the first uncrewed Mars test flights, while future iterations could reach 466 feet in height and deliver larger payloads critical for settlement. Ultimately, Musk stated that an aggressive timeline for a city on Mars could be as short as 30 years, as noted in a Space.com report.
“I think it can be done in 30 years, provided there’s an exponential increase in the tonnage to Mars with each successive Mars transfer window, which is every two years. Every two years, the planets align and you can transfer to Mars.
“I think in roughly 15, but maybe as few as 10, but 10-15-ish Mars transfer windows. If you’re seeing exponential increases in the tonnage to Mars with each Mars transfer window, then it should be possible to make Mars self-sustaining in about call it roughly 25 years,” Musk said.
Starship’s role
Starship has flown in a fully stacked configuration ten times, most recently in August when it completed its first payload deployment in orbit. The next flight will close out the Version 2 program before transitioning to Starship Version 3, featuring Raptor 3 engines and a redesigned structure capable of lifting over 100 tons to orbit.
While SpaceX has demonstrated Super Heavy booster reuse, Ship reusability remains in development. Musk noted that the heat shield is still the biggest technical hurdle, as no orbital vehicle has yet achieved rapid, full reuse.
“For full reusability of the Ship, there’s still a lot of work that remains on the heat shield. No one’s ever made a fully reusable orbital heat shield. The shuttle heat shield had to go through nine months of repair after every flight,” he said.
