Paper from OpenAI says hallucinations are less a problem with LLMs themselves & more an issue with training on tests that only reward right answers. That encourages guessing rather than saying “I don’t know” If this is true, there is a straightforward path for more reliable AI.
Legit: whoever came up with the idea of having an LLM (which was not natively great at Math at all) learn to write code (which it does super well) to solve complex problems, is a genius. That one insight unlocked mountains of opportunity.
In just 2 hours, our discharge petition to force a vote on releasing the Epstein files garnered 134 signers. We are over halfway to 218. Thank you to @RepBoebert, @RepMTG, and @RepNancyMace for signing the petition and standing up for the victims. Where are the men?
Robert F. Kennedy Jr. is endangering the health of the American people now and into the future. We need science at the CDC. Not conspiracy theories. Kennedy must resign. Read my new piece in @nytimes:

Great job working together!
Attracting global talent is not China’s strength—the world’s best would rather join the United States. But if America abandons openness, it will squander one of its biggest advantages and decline into a second-rate power. marginalrevolution.com/marginalrevolu…
I don't think ICE should detain US citizens for days on end with no hearings, no contact with family or attorneys, and no explanations.

🚨 JUST IN: Trump administration directly intervened at Israel’s request to release Israeli cybersecurity official Tom Alexandrovich, charged with sex crimes against children and give him safe passage to Israel.
Increasingly, the findings of controlled experiments go much further: doctors with off-the-shelf AI outperform those without in diagnostics… but AI alone outperforms doctors. Harder to know what to do with that. What systems or interfaces will result in better human-AI teams?

One subtle reason why the market size for AI Agents is going to be bigger than we realize is there are many use-cases where running multiple agents in parallel to solve the same problem is valuable. This was effectively never possible with most knowledge work before. It just…
Emergency powers are the lifeblood of authoritarians. Once established in law, they’re nearly impossible to revoke because a president can veto any bill curtailing the power. We always live under dozens of active “national emergencies,” almost none of which are true emergencies.
Totally agree. The plateau is nowhere in sight and like other hardware in the past, it will likely never stop, but I feel like there is a threshold that will be met where products bloom and additional improvements to the underlying tech take a back seat.

Goldman's latest (still very early) analysis of tariff effects thru June 2025: -Foreign exporters absorbed 14% of US tariffs -US companies ate 64% -US consumers ate 22% -Protected US companies also raised prices -Consumers will see bigger price increases (70%) thru the Fall
The Epstein files are not a hoax. The Speaker adjourned Congress early to avoid the topic, but we will not forget. When the House returns from August recess, I can begin collecting the 218 signatures required to force a vote on binding legislation to release the files.
This guy was surgeon general in Trump's first term. And he says RFK Jr. is killing people.
