Silicon Valley’s sudden willingness to consider taking more reputational risk arrives as tech stocks are tumbling

A chatbot that pointed to one answer directly from Google could increase its liability if the response was found to be harmful or plagiarized.

AI has been through several hype cycles over the past decade, but the furor over DALL-E and ChatGPT has reached new heights.

Soon after OpenAI released ChatGPT, tech influencers on Twitter began to predict that generative AI would spell the demise of Google search. ChatGPT delivered simple answers in an accessible way and didn’t ask users to rifle through blue links. Besides, after a quarter of a century, Google’s search interface had grown bloated with ads and marketers trying to game the system.

Inside big tech companies, the system of checks and balances for vetting the ethical implications of cutting-edge AI isn’t as established as privacy or data security. Typically teams of AI researchers and engineers publish papers on their findings, incorporate their technology into the company’s existing infrastructure or develop new products, a process that can sometimes clash with other teams working on responsible AI over pressure to see innovation reach the public sooner.

Chatbots like OpenAI routinely make factual errors and often switch their answers depending on how a question is asked

To Timnit Gebru, executive director of the nonprofit Distributed AI Research Institute, the prospect of Google sidelining its responsible AI team doesn’t necessarily signal a shift in power or safety concerns, because those warning of the potential harms were never empowered to begin with. “If we were lucky, we’d get invited to a meeting,” said Gebru, who helped lead Google’s Ethical AI team until she was fired for a paper criticizing large language models.

Rumman Chowdhury, who led Twitter’s machine-learning ethics team until Elon Musk disbanded it in November, said she expects companies like Google to increasingly sideline internal critics and ethicists as they scramble to catch up with OpenAI.“We thought it was going to be China pushing the U.S., but looks like it’s start-ups,” she said.

An hour of study tonight, an hour on the weekend, another session a week from now: such so-called spacing improves later recall, without requiring students to put in more overall study effort or pay more attention, dozens of studies have found.

“The idea is that forgetting is the friend of learning,” said Dr. Kornell. “When you forget something, it allows you to relearn, and do so effectively, the next time you see it.”

cognitive scientists see testing itself — or practice tests and quizzes — as a powerful tool of learning, rather than merely assessment. The process of retrieving an idea is not like pulling a book from a shelf; it seems to fundamentally alter the way the information is subsequently stored, making it far more accessible in the future.

“Testing not only measures knowledge but changes it,” he says — and, happily, in the direction of more certainty, not less.

“Testing has such bad connotation; people think of standardized testing or teaching to the test,” Dr. Roediger said. “Maybe we need to call it something else, but this is one of the most powerful learning tools we have.”

The harder it is to remember something, the harder it is to later forget. This effect, which researchers call “desirable difficulty,”

It is not cheapIt is not quickYou need to invest in building up your own staff expertiseIt will bring additional problems that you didn’t have beforeStudents will need different types of support

the main issue here is the cut in academic staff and the outsourcing of expertise. Invest in your staff.

a better solution is to invest in staff (and here institutions might want to get expertise in to help), use OER for content, and make strategic decisions that have as their basis the belief that online, distance ed is a useful, valid form of education.

Generally these papers are just pumped-up versions of the five-paragraph essay, with filler added. Thesis-driven, argumentative, like the newspaper editorials the genre is based on, this "researched writing" promises to solve big questions with little effort: "Reproductive rights resolved in five pages!"

Actual writing related to research is modest, qualified, and hesitant

our actual model involves elaborately respectful conversation, demonstrating sensitivity to the most nuanced claims of previous researchers

Academic, legal, medical, and business writing has easily understandable conventions. We responsibly survey the existing literature, formally or informally creating an annotated bibliography. We write a review of the literature, identifying a "blank" spot ignored by other scholars, or a "bright" spot where we see conflicting evidence. We describe the nature of our research in terms of a contribution to the blank or bright spot in that conversation. We conclude by pointing to further questions.

Millions of pieces of research writing that aren’t essays usefully circulate in the profession through any number of sharing technologies, including presentations and posters; grant and experiment proposals; curated, arranged, translated, or visualized data; knowledgeable dialogue in online media with working professionals; independent journalism, arts reviews, and Wikipedia entries; documentary pitches, scripts and storyboards; and informative websites.

real researchers don’t write a word unless they have something to contribute. We should teach our students to do the same

Can we transform this credentialing process? And in fact the ideal would be to separate out the idea of proving your knowledge from the way you acquire that knowledge

Employers have decided that having the breadth of knowledge that's associated with a four-year degree is often something they want to see in the people they give that job to. So instead of testing for that different profession, they'll be testing that you have that broader exposure

that failing student is a disaster for everyone

What is it that we need to do to strengthen this fundamental part of our country that both in a broad sort of economic level and an individual-rights level is the key enabler. And it's amazing how little effort's been put into this. Of saying, OK, why are some teachers at any different level way better than others? You've got universities in this country with a 7-percent completion rate. Why is it that they don't come under pressure to change what they're doing to come up with a better way of doing things?

We bet on the change agents within the universities. And so, various universities come to us and say, We have some ideas about completion rates, here are some things we want to try out, it's actually budget that holds us back from being able to do that. People come to us and say, We want to try a hybrid course where some piece is online, some piece is not, and we're aiming this at the students that are in the most need, not just the most elite. So that's who we're giving grants to, people who are trying out new things in universities. Now the idea that if you have a few universities that figure out how to do things well. how do you spread these best practices, that's a tough challenge. It's not the quite same way as in the private sector that if somebody's doing something better, the price signals force that to be adopted broadly. Here, things move very slowly even if they are an improvement.

Q. Some of what you've been talking about is getting people to completion by weeding out extraneous courses. There's a concern by some that that might create pressure to make universities into a kind of job-training area without the citizenship focus of that broad liberal-arts degree.

it is important to distinguish when people are taking extra courses that broaden them as a citizen and that would be considered a plus, versus they're just marking time because they're being held up because the capacity doesn't exist in the system to let them do what they want to do. As you go through the student survey data, it's mostly the latter. But I'm the biggest believer in taking a lot of different things. And hopefully, if these courses are appealing enough, we can get people even after they've finished a college degree to want to go online and take these courses.

Other countries are sending more kids to college. They're getting higher completion rates. They've moved ahead of us

There's nothing that was more important to me in terms of the kind of opportunity I had personally. I went to a great high school. I went to a great university. I only went three years, but it doesn't matter; it was still extremely valuable to me to be in that environment. And I had fantastic professors throughout that whole thing. And so, if every kid could have that kind of education, we'd achieve a lot of goals both at the individual and country level

One of the strengths of higher ed is the variety. But the variety has also meant that if somebody is doing something particularly well, it's hard to map that across a lot of different institutions. There aren't very many good metrics. At least in high schools we can talk about dropout rates. Completion rate was really opaque, and not talked about a lot. The quality-measure things are equally different. We don't have a gold standard like SAT scores or No Child Left Behind up at the collegiate level. And of course, kids are more dispersed in terms of what their career goals are at that point. So it's got some things that make it particularly challenging, but it has a lot in common, and I'd say it's equally important to get it right
