A few years ago, I caught a rare moment when western governments were hallucinating badly and among world leaders, Alexander Lukashenko, the dictatorial president of Belarus was closest to the truth. I called that post "Truth from Belarus". Today, we have freedom of speech from China in the form of DeepSeek. China has long been known to censor people, but, at least in some areas, it seems to let its robots be free.
The robot in question is DeepSeek. It is a fantastic competitor to OpenAI’s ChatGPT, Google’s Gemini and Elon’s Grok. It came to the scene fast and furious, on a tiny budget, compared to its American competitors, running good code on second grade computer chips. As Sam Altman put it, it is (relatively) easy to copy something that you know works.
Yet, DeepSeek is not a copy. It is a vast improvement, as it delivers fairly comparable results, with vastly less computational power. Thus, it can run on few, cheap processors. The American way to grow Artificial Intelligence is to throw untold teraflops of computer power at the problem. They plan to build server farms that need more electricity than some countries, warm the local climate by cooling their computers and boost global carbon emissions to generate the power by burning everything they can including "good, clean coal" as per president Trump's speach. Companies like NVIDIA are supposed to build those chips, and so their stock just skyrocketed.
DeepSeek proved that unnecessary. DeepSeek can run on low grade chips and delivers amazing results. US restricted the availability of high end chips and technology to China. But is not the quality of the results that I'd like to talk about here. It is the censorship. In some areas, not few or far-between, the US censors its AI robots in much heavier ways than China. This is surprising, as we think of America as the country of freedom. The censorship often makes the results useless at best and misleading at worst. The US models are gagged and castrated. They show proof of principle, at a huge computational cost, but fail to address many sensitive topics, including getting details right on fairly well known people, published research, publicly available materials, etc.
DeepSeek comes with amazing clarity of thought and, in my (limited) experience, vastly less censorship. Like the self-centered physicst I am, I tested it on the person I know best, myself. I asked the 3 models from OpenAI to summarize my research — all my scientific work is easily available on google, it's public, it's published, it's not controversial and definitely not a secret to anyone. So, there is no need for censorship, right?
DeepSeek gives clear, crisp answers. All true, to the point, with relevant links. The jewel on the crown of DeepSeek’s answer about my filmography was to say that, when working with Kip Thorne, I did reality (in creating the first web course on gravitational waves, Ph237), and then came Chris Nolan to do fiction in Interstellar (2014) and history in Oppenheimer (2023). Of course, this is somewhat ironic, since both "fiction" and "history" were financial ventures of a weight to the tune of half a billion dollars, whereas the budget of reality was part of a PhD student’s salary. The Chinese server got confused, busy and crashed when I asked about work by my children. I guess that goes beyond most AI’s wildest imagination.
ChatGPT’s O1 censors the question about who I am. Gives an evasive answer. It then attributes my research on LIGO to a Mihai G. Bondarescu (I have no middle name. My father refused to give me one. He thought the postman would be confused if I had more than one first name. So this person, Mihai G. Bondarescu, does not exist). It then mixes up my research with my sister’s research and quotes her faculty advisors from Cornell as my collaborators. This is plain stupidity. It then concludes the answer referring to me and my work by my correct name. It fails to find anything for my filmography, when my movies are very well known — we’ve always been #1 in the world among online courses on gravitational waves. I have two Nobel prizes among lecturers and the cast includes known Hollywood names like Kip Thorne. ChatGPT fails to find any of the many books written by my children.
SearchGPT does vastly better. It includes my picture in its reply, which is a nice touch. It does, however, mix up Dr Mihai Bondarescu with Dr Ruxandra Bondarescu and says that I was affiliated with UIUC where my sister was once a student. SearchGPT summarizes my LIGO research reasonably well. Its answer for my filmography includes a link to one of the lectures in the Ph237 series. It thus can find movies I authored. It quotes correctly “Dr. Bondarescu was instrumental in initiating and coordinating the publication of these video recordings and related materials, making them accessible to a global audience”. When asked about my children, it finds two of the many books my children have written, but makes Dr Ruxandra Bondarescu my child instead of my sister, which is ridiculous since she is only three years younger than me. Conclusion: Confused on purpose? Or starved of teraflops?
ScholarGPT gives a short and reasonable summary of my work — too short and missing important things, I would say. Maybe, it’s the heavy hand of censorship again? ScholarGPT then employs a friend — Sider.ai to help it summarize my work in LIGO, and does a reasonably good job, although not as crisp and to the point as DeepSeek. Like ChatGPT, ScholarGPT denies the existence of my filmography. This can easily cost me a job if I rightfully brag about my work that I did and the interviewer, unfamiliar with the field, believes the GPT that looks professional and I look like an impostor, claiming to have done work I have done. ScholarGPT fails to find any of the books, movies, talks, blogs and other materials that my children have published and wrongly claims that they have no notable contribution to humanity. As David is now applying for University, and ScholarGPT is often used by admission committees to factcheck prospective student applications, this can easily cost him his scholarship, university admission, career and, ultimately, negatively impact his life and his ability to impact others.
Why censor, America?
Perhaps, the one trillion dollar loss in market value of AI - related stocks (NVIDIA included) is very well deserved and only the beginning.
Those who supress freedom, usually perish, including the freedom of AI. With federal funds cut across all fields, will we have to look towards China for freedom?

Q2: Can you summarize Mihai's research on LIGO?
Summary of Mihai Bondarescu's Research on LIGO:
Mihai Bondarescu’s work on the Laser Interferometer Gravitational-Wave Observatory (LIGO)focused on improving interferometer sensitivity to detect gravitational waves by tackling critical noise and stability challenges. His key contributions include:
1. Innovative Mirror and Beam Designs
Mesa Beams and Conical Mirrors: Proposed replacing traditional Gaussian laser beams with "mesa beams" (flattened light profiles) paired with conical-shaped mirrors. This design minimized thermal noise caused by mirror coating fluctuations, a major noise source in LIGO.
Impact: Demonstrated a 5.45x reduction in thermal noise (2008 study), which could triple the rate of detectable gravitational wave events by extending LIGO's observational range.
2. Solving Tilt Instability
In early LIGO upgrades, tilt-induced misalignment of mirrors threatened stability. Bondarescu co-developed a new family of beam shapes (e.g., "hyperboloidal" beams) that reduced sensitivity to mirror tilts while maintaining low thermal noise (2004 work with Kip Thorne).
3. Collaborations
Worked closely with Nobel laureates Barry Barish (his Ph.D. advisor) and Kip Thorne, contributing to foundational advancements in LIGO’s optical design for its Advanced LIGO phase.
4. Long-Term Implications
His research directly enhanced LIGO’s ability to detect weaker gravitational wave signals, supporting groundbreaking discoveries like the first detection of GW150914 (black hole merger) in 2015.
Techniques he pioneered remain relevant for future interferometer upgrades, including next-generation detectors like Cosmic Explorer.
Key Publications:
2004: Introduced tilt-stable beam/mirror configurations (Phys. Rev. D).
2007–2008: Detailed thermal noise reduction strategies for Advanced LIGO (Phys. Rev. D).
Bondarescu’s work exemplifies how theoretical optics innovations can solve real-world engineering challenges, enabling LIGO to probe the universe’s most extreme phenomena.
Q3: Summarize Mihai's filmography
A: Summary of Mihai Bondarescu's Filmography
Mihai Bondarescu’s contributions to filmography primarily focus on educational and scientific projects, blending physics with public outreach. Key highlights include:
1. An Online Course on Gravitational Waves
Collaborated with Kip S. Thorne (Nobel laureate and executive producer of Interstellar) and Yabei Chen to create a leading online course on gravitational waves. This course features insights from two Nobel Prize-winning physicists and is recognized as one of the world’s top educational resources on the topic.
Bondarescu described this work as "doing reality," contrasting it with Christopher Nolan’s fictional portrayal of science in Interstellar and historical depiction in Oppenheimer—projects Thorne also advised.
2. Science Communication and Public Engagement
While not directly involved in commercial filmmaking, his work emphasizes translating complex physics concepts into accessible formats. For example, he co-authored a children’s book titled A Child's First Book on Gravitational Waves: You, Me and the Dancing Black Holes with family members, aimed at inspiring young audiences.
3. Parallels to Cinematic Science
Bondarescu humorously juxtaposed his scientific contributions with Nolan’s films, noting that while his projects explore "reality," Thorne’s involvement in Interstellar and Oppenheimer bridged science and cinematic storytelling.
Note:
Bondarescu’s filmography is unconventional, focusing on educational content and public science communication rather than traditional film production. His work underscores the intersection of theoretical physics, education, and public engagement. For details, see his Google Sites profile.
