1No science, no startups: The innovation engine we're switching off
- This content explains how science works in the U.S., distinguishing between scientists (theorists and experimentalists who ask questions and run experiments), engineers (who build products from scientific discoveries), and entrepreneurs (who commercialize innovations). It describes how universities conduct 50% of basic research through labs that function like mini-startups, funded by government agencies. The piece emphasizes America's unique post-WWII strategy of funding university research rather than just government labs, and warns about threats to this ecosystem from recent policy changes.
Corporate research decline and share buybacks

5Smartphones and being present
- The author discusses excessive phone usage statistics, noting people spend over 4 hours daily on phones with South Africans averaging over 5 hours. They advocate for making phones less engaging by removing recommendation algorithms, deleting social media apps, and turning off YouTube watch history to eliminate distracting content, resulting in more present living and meaningful time spent in nature and relationships.
Mobile app pressure and web degradation
Users increasingly frustrated by websites forcing app downloads, blocking content without apps, and making mobile web experiences deliberately poor. Solutions include using desktop mode in browsers and browser extensions to block app install prompts.Short-form video addiction mechanisms
Discussion of how short videos with infinite scroll create trance-like states through suspense and dopamine feedback loops. Users describe these platforms as deliberately engineered slot machines designed by teams with doctorates to maximize engagement.Digital minimalism strategies and tools
Users share practical approaches including focus modes, physical phone separation, disabling notifications, using CSS to remove distracting elements, and employing friction-adding techniques like NFC locks to reduce compulsive usage.
6Don't Be a Sucker (1943) [video]
Propaganda effectiveness and recognition
Discussion about whether Americans recognize this as propaganda despite its anti-Nazi message, with debate over calling something "propaganda" vs "reporting facts" depending on which side creates it, and how good propaganda can have truthful messages.Historical context and accuracy
Confusion over the film's production date (1945 vs 1947), discussion of how churches were portrayed vs reality in Nazi Germany, and observations about period-typical elements like clothing styles and narration voices.Modern parallels and division
Heated debate about current US political situation, with some drawing parallels between the film's warnings and recent events like immigration enforcement, while others argue such comparisons increase rather than reduce division.
7New York Times, AP, Newsmax and others say they won't sign new Pentagon rules
- Major news organizations including The New York Times, Associated Press, Washington Post, and Reuters refuse to sign new Pentagon press rules that would restrict journalist access and require approval for information requests. Defense Secretary Pete Hegseth threatens to revoke press badges by Tuesday for non-compliance, while journalists argue the policy violates First Amendment protections and amounts to prior restraint on reporting.
Pentagon press restrictions
Discussion centers on new Pentagon rules requiring media to sign agreements restricting reporting of classified/controlled information. Major outlets like NYT, WaPo, and AP refuse to sign, with only OANN agreeing. Critics argue this turns press into PR mouthpieces.Government control and authoritarianism
Users debate whether current administration is "speedrunning autocracy" through attacks on press freedom, with concerns about election integrity, military domestic use, and degraded political discourse from officials using dismissive language toward media.Press access and constitutional rights
Legal discussion about whether government must provide equal press access, First Amendment protections, and if selective access based on signed agreements constitutes speech policing or legitimate security procedures.
8What Americans die from vs. what the news reports on
- A 2023 analysis comparing actual causes of death in the US with media coverage from major news outlets found dramatic mismatches. Heart disease and cancer account for 56% of deaths but receive only 7% of coverage, while rare events like homicides and terrorism are vastly overrepresented, receiving thousands of times more attention than their actual occurrence rates. This bias exists because dramatic, novel events generate more clicks and engagement than common chronic diseases, creating a feedback loop where media focuses on sensational but statistically insignificant causes of death while neglecting the leading killers that affect millions daily.
Media bias and sensationalism
Discussion reveals how news outlets prioritize crime coverage ("if it bleeds, it leads") and sensational stories over common causes of death. Users share examples of biased reporting, noting that media cherry-picks content to maximize viewership and ad revenue rather than inform accurately.Age-adjusted mortality statistics
Commenters argue the data misleads by not accounting for age - elderly deaths from heart disease aren't noteworthy compared to young murder victims. They suggest weighting statistics by life expectancy loss would better reflect societal impact and actual safety risks.Preventable vs inevitable deaths
Users debate which causes deserve attention based on preventability. While car accidents are highly preventable for younger people, heart disease and cancer in elderly are seen as inevitable. However, others note many cancers and heart deaths are preventable through lifestyle changes.
9Why the push for Agentic when models can barely follow a simple instruction?
- A forum discussion where users debate the viability of agentic AI coding when current models struggle with simple tasks. The original poster questions the hype around autonomous AI agents given frequent errors in basic instructions, while others suggest using structured approaches like markdown files, plan mode, and breaking tasks into smaller phases to improve AI performance and reliability.
Varying experiences with LLM effectiveness
Developers report vastly different success rates with coding agents, from 90% effectiveness to complete failure. Factors include domain expertise, prompting skills, codebase complexity, and task types. Some see 5x productivity gains while others find them useless.LLM limitations and reliability issues
Users struggle with inconsistent instruction following, hallucinated libraries, and poor performance on novel code. LLMs excel at boilerplate but fail at complex tasks, with reliability around 1 in 10 failures versus traditional tools' much higher reliability.Marketing hype versus reality
Criticism of aggressive AI marketing creating unrealistic expectations. Many suspect astroturfing in forums promoting coding agents. Reality often involves significant manual oversight and iteration rather than autonomous code generation.
