Large language models can do jaw-dropping things. But nobody knows exactly why.
(03/04/2024)
- Despite advancements, scientists remain uncertain exactly how AI models achieve certain capabilities.
- Two years ago, OpenAI (ChatGPT) researchers discovered an unexpected learning pattern called “grokking” where models failed at tasks until a sudden unexplainable breakthrough.
- An example of such a breakthrough is models not only solving complex math problems, but also learning how to solve the problems in French.
- Developing these models is akin to a chef trying different ingredients to create new recipes; scientists copy what works from others without asking “how”.

Massive pro-Palestinian college protests bring rare surge in discipline
(05/06/2024)
- Recent pro-Palestinian protests across America’s college campuses have led to severe disciplinary actions, including suspensions and expulsions, reminiscent of responses to 1960s Vietnam and 1980s Apartheid protests.
- Unlike previous demonstrations, today’s protests pit supportive and opposing student groups against each other, with accusations of antisemitism adding complexity.
- This divisiveness, combined with pressures on university presidents who risk job loss, marks a distinct shift from past protests, where opposition was less polarized and personal stakes for leadership were lower.
Meta Advertisers Say Automated System Has Been Glitchy for Weeks
(04/10/2024)
- Over the past two months, digital advertisers have complained about the declining effectiveness of Meta’s (Facebook, Instagram parent company) digital ads.
- Ad buyers report that costs have doubled or tripled while the effectiveness of campaigns has diminished, prompting some to shift more ad spending to Google and TikTok.
- Some believe that the Chinese e-commerce giant Temu’s billion-dollar expenditure on digital ads to expand its US operations has driven up the cost of digital advertising.
- Meta generates over $100B per year from digital ads.
AI Boom Reawakens Silicon Valley’s Housing Market
(02/10/2024)
- The rise in artificial intelligence (AI) has rejuvenated Silicon Valley’s housing market.
- More first-time buyers, many who work for major tech companies, can now afford million-dollar homes thanks to rising share prices which account for a big chunk of tech industry salaries.
- The return-to-office push and slight dip in mortgage rates have also boosted Northern California housing.
- Among the 50 biggest US metros, San Jose (median sales price $1.3M) leads in home-sales pace with 61% of new listings under contract within 14 days.
Why Americans’ ‘YOLO’ spending spree baffles economists
(12/01/2023)
- Despite high interest rates, inflation, and shrinking savings, US spending has perplexed economists by surging, as evidenced by the recent 9.6% year-over-year increase in Cyber Monday sales.
- Consumer spending growth accounted for most of the 4.9% increase in Q3 GDP.
- This growth largely derives from the “unprecedented” increase in accumulated US household savings following government pandemic stimulus programs.
- However, this trend will eventually reverse as student loan repayments resume and growing credit card debt limit future spending power.
A Treasure May Be Off the Coast of Colombia, but Who Can Claim It?
(11/10/2023)
- The San José, a Spanish cargo vessel ship sunk in 1708 by the British with treasure currently estimated at $20 billion, has ignited a complex international dispute over its claim.
- While Colombian President Gustavo Petro plans to recover it, this initiative faces opposition from archaeologists, Spain, indigenous groups, and a US search group claiming 50% discovery rights for locating the shipwreck in the 1980s.
- The article details why the recoverable treasure’s value is probably inflated and the justification behind ownership claims.
What Happens to Your Body on No Sleep?
(04/02/2019)
- Scientists have found that the effects of acute sleep deprivation, or all-nighters, kicks in after being awake for 16-18 hours straight.
- The first sign is a sluggish mind, with reaction times lagging to the equivalent of being legally drunk by the 24th hour awake.
- After 24 hours, your brain starts forcing you into 10-20 second periods of “micro-sleep”.
- After 35 hours, the brain’s emotion-emitting amygdala becomes 60% more reactive and the ability to regulate emotions declines.
- Hallucinations are common after 48 hours awake.
