OpenAI Proposes “Right to AI” Researchers from OpenAI have put forward an industrial policy for artificial intelligence and it’s quite a read. They propose a legally recognised “Right to AI”, meaning broad public access to powerful systems, backed by government-funded compute resources so researchers, startups, and public institutions can run models themselves, rather than rely on a few companies. To make this reality, they want to see an expansion of electricity supply for data centres by fast-tracking nuclear and renewables. They also suggest a national wealth fund that captures a share of AI-driven profits and redistributes it to citizens, alongside taxes or levies on highly automated systems, effectively a “robot tax”. Of course none of that has any chance of happening, but OpenAI can now claim they care about the common man.

Yesterday in @AnnalsofIM, a new risk-stratified analysis found that different people get different benefits from limiting #SaturateFats. Cue the all-or-nothing #FalseDichotomies and another painful assault on the nuance of nutrition science. conscienhealth.org/2025/12/n…

#RealWorldData advocates facing challenges addressing sources of bias suggest causal modelling as a solution. Doesn’t work. Comparison of 19 modelling studies with #RCTs showed 42% differed in direction and 47% of confidence intervals didn’t include RCT estimate. pubmed.ncbi.nlm.nih.gov/3170…

Impressive new Canadian #pediatric #obesity #guidelines are out today. The authors grounded them in the best science and crafted them with values of children and families at the center. What's missing? Resources to make them real. HT: @ObesityCan conscienhealth.org/2025/04/n…

Thanks, Arun! Here’s the link to the California Executive Order directing state agencies to investigate health risks associated with UPF, synthetic food dyes, and other additives, and to recommend public actions. Highlighted text in the figure below gov.ca.gov/wp-content/upload…

Amazing to watch every outlet attribute these findings to UPFs and seed oils when the study doesn't even look at this. The assumption that eating more linoleic acid -> higher tissue arachidonic acid enrichment has fueled so many handwavey hypotheses despite metabolic regulation

The good idea comes when one person feels comfortable enough to say something that might make them look stupid and their friend is open enough to recognize its potential.

What leads us to ignore experts isn't their knowledge. It's their arrogance. Evidence: Scientists are more credible when they admit what they don't know, acknowledge what they got wrong, and update their views. Trust is earned by expressing humility, not by asserting authority.

🔥 Reminder: AI systems are NOT neutral; they will reflect the ideology of their creators (as with any technology). Critical thinking remains an ESSENTIAL skill.
