A former Tesla intern has shared his thoughts on his time at the company’s Gigafactory in Grünheide, Germany, calling the experience a “journey into the heart of innovation,” among other things.
Silas Heineken, a 17-year-old resident of Grünheide, shared a post on X on Monday detailing his internship experience at the Tesla Gigafactory, dubbed Giga Berlin. In it, Heineken thanks those involved in his internship, specifically noting that he had the chance to learn about the Assembly, Battery Cell, and Powertrain R&D departments.
“The last three weeks have been some of the most inspiring time of my life,” Heineken writes. “Four years after Tesla came to my hometown amidst a never-ending story of controversies, I finally got the opportunity to see for myself. I witnessed what the public doesn’t see, and perhaps doesn’t want to see. People from all over the world work together here, tackling the seemingly impossible and solving the problems of our current times, all in an atmosphere of joy and enthusiasm.”

He also said that the experience has helped to shape his own future plans, adding that it helped him see the “future-oriented environment and spirit that permeate the labs, offices, and production lines at Giga Berlin.”
“This internship wasn’t just a learning experience; it was a journey into the heart of innovation that has reshaped my future aspirations,” Heineken adds in the post. “A big thank you to everyone who was directly and indirectly involved in making this possible!”
In another post, Heineken also highlighted a handful of things that have come to the Grünheide community since Tesla built the Gigafactory. One such mention includes the solar-powered lights Tesla sponsored and installed at a local skate park, featuring dimmable LEDs and automatic motion sensors.
Along with internships, Tesla’s Gigafactory regularly hosts workshops for students, and other events for the families of employees. Heineken’s thoughts on the Tesla internship experience also come just over a month after environmental activists set a fire at Gigafactory Berlin, causing a production halt and garnering an investigation from German authorities and a visit from CEO Elon Musk.

T-Mobile’s Starlink cellular doubles as free 5G trial for rival users

T-Mobile’s Starlink cellular is set to deliver satellite connectivity to users on rival carriers. The Starlink cellular beta program could double as a free trial for T-Mobile’s 5G network, blending space-based innovation with a strategic push to attract new customers. T-Mobile’s Starlink cellular service will launch soon, aiming to showcase both Starlink’s capabilities and T-Mobile’s terrestrial network.
“The wait is almost over,” T-Mobile announced in a Wednesday email to those who signed up for free beta access to the cellular Starlink service. “Our phone partners have been hustling to get more phones satellite-optimized, and in just a couple weeks, you’ll be invited to the beta.”
The Starlink cellular program includes “50GB of high-speed data and unlimited texts,” offering a robust test of T-Mobile’s 5G network alongside Starlink’s satellite connectivity. This package mirrors T-Mobile’s existing three-month free trial, which provides 50GB of premium mobile data via eSIM, allowing users to try T-Mobile without switching from their current provider.
Starlink cellular’s availability to rival carrier users via eSIM is a key draw, enabling seamless access to T-Mobile’s network and Starlink’s satellite service. T-Mobile sweetens the deal with perks like “$5 movie tickets, 25% off concert tickets, travel discounts, and T-Mobile Tuesdays for free stuff and great perks every week.” These incentives underscore T-Mobile’s strategy to convert beta testers into full-time customers.
Last week, T-Mobile reduced Starlink cellular’s price to $10 per month for both its customers and those on rival carriers, enhancing affordability. The company’s exclusive U.S. partnership with SpaceX gives it a head start in satellite connectivity. Meanwhile, competitors AT&T and Verizon, collaborating with AST SpaceMobile, may lag by a year or two due to fewer satellites.
By offering rival carrier users a free trial of its 5G network through the Starlink cellular beta program, T-Mobile positions itself as a leader in terrestrial and satellite connectivity. The initiative highlights the potential of SpaceX’s Starlink and leverages T-Mobile’s network strengths to capture a broader market, setting the stage for a new era of hybrid connectivity.

Elon Musk’s OpenAI lawsuit clears hurdle as trial looms
Elon Musk says OpenAI betrayed its nonprofit mission. Who should steer AI’s future—visionaries or shareholders?

Elon Musk’s lawsuit against OpenAI and CEO Sam Altman has cleared a major hurdle. Judge Yvonne Gonzalez Rogers of the Northern District of California recently rejected OpenAI’s bid to dismiss the case, setting the stage for a high-stakes trial over the AI giant’s for-profit conversion. The ruling intensifies the rivalry between two tech titans vying for dominance in artificial intelligence (AI).
Elon Musk is an OpenAI co-founder who provided significant early funding. In the lawsuit, Musk alleged that OpenAI’s shift from a non-profit to a for-profit entity violates contractual obligations and constitutes fraud. Last year, The lawsuit was filed against Altman, OpenAI, and its key investor, Microsoft, aiming to block the conversion to a for-profit company.
In March, a ruling denied Musk’s request for a preliminary injunction. However, Judge Rogers recently expedited the trial and set it for March 2026. On Thursday, she dismissed some claims but upheld key allegations, allowing the case to proceed.
“Musk adequately alleges that the defendants promised to maintain OpenAI’s non-profit status and structure in order to obtain his contributions and that they intended to do so in order to obtain the capital needed to create a for-profit venture to enrich themselves,” Gonzalez Rogers wrote.
She also rejected OpenAI’s attempt to dismiss Musk’s claim of an implied contract. “Although there is no express contract, Musk adequately pleads in the alternative that there is an implied-in-fact contract,” the California judge noted.
“In the world of litigation, this is a big win,” said a person close to Musk, highlighting the retention of “big-ticket items” like the fraud allegation.
OpenAI, which can appeal the decision, countersued Musk last month. It claims Musk’s lawsuit is a “bad-faith” effort to hinder its progress and benefit his AI venture, xAI.
OpenAI’s push to become a for-profit public benefit corporation aims to streamline fundraising but has sparked a backlash from AI experts like Geoffrey Hinton. Former employees warn that OpenAI’s change of direction could prioritize profits over its mission to advance AI for humanity’s benefit.
Financial Times attempted to contact OpenAI and its biggest investor, Microsoft. OpenAI declined to comment, and Microsoft did not respond.
As Elon Musk and OpenAI head toward trial, the outcome could reshape the AI landscape, with implications for governance, innovation, and the balance between profit and public good.

Neuralink device gets FDA recognition for speech restoration
Neuralink device gets FDA’s ‘breakthrough’ designation. With Link, a man with ALS now types, navigates, and speaks.

Neuralink’s brain-computer interface (BCI) device, Link, has secured the U.S. Food and Drug Administration’s (FDA) “breakthrough” designation for restoring communication in patients with severe speech impairment. This milestone advances Elon Musk’s vision of merging human cognition with technology.
The Link device targets individuals with neurological conditions like Amyotrophic Lateral Sclerosis (ALS), stroke, spinal cord injury, cerebral palsy, and multiple sclerosis. In a recent X video, Neuralink’s third PRIME Study participant, Bradford G. Smith, who lives with ALS, showcased the device’s potential.
Using Link, Smith regained his ability to communicate, leveraging AI to narrate with a synthesized version of his former voice. “I am typing this with my brain,” Smith wrote. “It is my primary communication.”
Smith edited the X video with the help of Link. In the video, he demonstrated how Link enabled him to control a computer cursor to communicate, highlighting the BCI’s ability to interface with external devices.
Before Link, Smith relied on an eye tracker, which limited communication in bright settings and restricted his mobility. Now, Neuralink’s implant enables him to connect more freely. His experience shows Neuralink’s progress in empowering paralyzed individuals and those with neurodegenerative diseases through revolutionary assistive solutions.
The company is also exploring applications for vision restoration and other health challenges. In 2024, Neuralink received the FDA’s ‘breakthrough device’ tag for its Blindsight device. Elon Musk explained that Blindsight would help people who have lost both eyes and function in their optic nerve to see. However, Neuralink’s current focus remains on mobility and communication.
Neuralink recently expanded its patient registry to include participants worldwide. The PRIME Study, likely the primary target for new registrants, tests Link’s base capabilities. Meanwhile, the CONVOY study explores Link’s ability to control robotic devices, like an assistive robotic arm. This broader access underscores Neuralink’s commitment to scaling its trials.
The company is reportedly preparing for a $500 million funding round, with preliminary talks valuing Neuralink at $8.5 billion pre-money and potentially $9 billion post-money, though terms remain fluid. Neuralink has not commented on the speculation about funding.
By earning FDA breakthrough status, Neuralink positions Link as a transformative tool for those with severe speech impairments. Smith’s experience illustrates its potential to restore independence, while ongoing trials and funding efforts signal the company’s ambition to redefine human-technology interaction for neurological conditions and beyond.
