Uncensored chatbots provoke a fracas over free speech

Published Tue, 04 Mar 2025 04:28:46 GMT

Artificial intelligence chatbots have lied about notable figures, pushed partisan messages, spewed misinformation or even advised users on how to commit suicide.To mitigate the tools’ most obvious dangers, companies such as Google and OpenAI have carefully added controls that limit what the tools can say.Now, a new wave of chatbots, developed far from the epicenter of the AI boom, are coming online without many of those guardrails — setting off a polarizing free-speech debate over whether chatbots should be moderated, and who should decide.“This is about ownership and control,” Eric Hartford, a developer behind WizardLM-Uncensored, an unmoderated chatbot, wrote in a blog post. “If I ask my model a question, I want an answer, I do not want it arguing with me.”Several uncensored and loosely moderated chatbots have sprung to life in recent months under names such as GPT4All and FreedomGPT. Many were created for little or no money by independent programmers or teams of volunteers,...

Q & A: What you need to know about new Alzheimer’s drug

Published Tue, 04 Mar 2025 04:28:46 GMT

This week the U.S. Food and Drug Administration approved the drug lecanemab after research showed it slowed the progression of Alzheimer’s disease in some patients with mild cognitive impairment.This is undoubtedly a breakthrough for treatment of an irreversible, progressive brain disorder affecting more than 6.5 million Americans. While the drug was granted so-called accelerated approval in January, full FDA approval means wider coverage by Medicare so it can better reach patients.Named Leqembi, lecanemab’s approval has triggered less controversy than a related drug called Aduhelm, or aducanumab, because its clinical trial results are more definitive.With help from Stanford and UC San Francisco experts, we answer questions about the new drug.Q: What is lecanemab?A: It’s a drug that is designed to remove amyloid beta, a sticky plaque that builds up in the brain in people with Alzheimer’s disease, causing disease progression. It is the first anti-amyloid treatment to earn...

Borenstein: Why Bay Area transit bailout deal is likely doomed to fail

Published Tue, 04 Mar 2025 04:28:46 GMT

When Gov. Gavin Newsom and the state Legislature agreed on a $5.1 billion statewide package to bail out public-transit systems, they missed an opportunity in the Bay Area to impose meaningful reform on wasteful spending and a confusing web of 27 transit agencies.The region needs a functioning, fiscally responsible and coordinated transit system to help unclog freeways and reduce carbon emissions. Clearly what we have now is not working. Traveling by bus, train or ferry involves struggling with a confusing maze of agencies, schedules, uncoordinated connections and differing fare structures.Transit was used for only 12% of all commute trips in 2018, while 75% used cars. That was before the pandemic struck and transit patronage plummeted.Meanwhile, Bay Area residents pay dearly through taxes, tolls and fares for transit agencies that have some of the proportionately highest administrative expenses in the country and costliest and slowest capital projects.Rather than directly address th...

McEnery: San Jose needs a common sense approach to BART extension

Published Tue, 04 Mar 2025 04:28:46 GMT

The multi-billion dollar project to extend BART six miles into the heart of San Jose is about to begin. One question must be answered: Should it?It is said that you should never start a project without knowing the reason why. We must have that answer and another about the commitment of an accountable leadership, not a board of elected officials from other places.They should also have the judgment to see the facts and do their job of looking at the financial reality of both construction and operation. There can be no magical thinking, no manna from heaven hopes, and they must be ready to commit something beyond “thoughts and prayers” to those who will be collateral damage in a rush to attend this ground breaking.The billion-dollar VTA boring mole will soon be traveling beneath our streets, operated by the scandal-plagued BART management team. This is a group dominated by its unions and an assortment of contractors and consultants. To add to that, the politicized BART board and manage...

Why the Stop Trump effort all comes down to South Carolina

Published Tue, 04 Mar 2025 04:28:46 GMT

South Carolina has long been the state most likely to predict the eventual winner of the Republican presidential nomination.This cycle, it will likely be even more crucial.The state Republican Party’s decision to schedule its election for Feb. 24 means the first-in-the-South primary will potentially take place more than a month after Iowa and New Hampshire. That open stretch means South Carolina is poised to carry more weight than ever in determining whether former President Donald Trump’s march to a third consecutive nomination will face a sustained threat stretching past the early states and into the meat of the primary calendar.Consider this: The GOP primary starts in Iowa in mid-January. New Hampshire votes the week after, perhaps on Jan. 23. Then there’s a long gap until South Carolina. While Nevada Republicans could hold their caucuses either before or immediately after South Carolina, the larger electorate and delegate haul from South Carolina has focused far more attention o...
