The Brief

A few months ago, a high school English teacher in Los Angeles Unified noticed something different about his students’ tests. Students who had struggled all semester were suddenly getting A’s. He suspected some were cheating, but he couldn’t figure out how.

Until a student showed him the latest version of Google Lens.

Google had recently made the visual search tool easier to use on the company’s Chrome browser. When users click on an icon hidden in the tool bar, a moveable bubble pops up. Wherever the bubble is placed, a sidebar appears with an artificial intelligence answer, description, explanation or interpretation of whatever is inside the bubble. For students, it provides an easy way to cheat on digital tests without typing in a prompt, or even leaving the page. All they have to do is click.

“I couldn’t believe it,” said teacher Dustin Stevenson. “It’s hard enough to teach in the age of AI, and now we have to navigate this?”

Keeping up with students’ methods of cheating has always been a cat-and-mouse game for teachers. But some now say that AI tools, particularly Lens, have made it impossible to enforce academic integrity in the classroom — with potentially harmful long-term effects on students’ learning.

‘A terrible idea’

Lens has been around for nearly a decade. It’s the camera technology that scans QR codes or identifies objects in photos. But as AI has evolved, its uses have expanded, and Google has made it more available to users, especially those using Chrome, the Google browser.

During the COVID school closures, most school districts in California gave students Chromebook laptops to do remote work. Thousands of those laptops were actually donated by Google. After schools reopened for in-person learning, schools kept using the Chromebooks, making them an integral part of classroom instruction.

Millions of California’s 5.8 million K-12 students use Chromebooks, making it by far the most popular laptop option in schools.

For William Heuisler, a high school ethnic studies teacher in Los Angeles, the ubiquity of Chromebooks was the first red flag.

“After COVID-19, it was clear that Chromebooks were a terrible idea in my classroom,” Heuisler said. Students used the laptops to play games during class, watch soccer matches and otherwise focus on anything but the lesson plan.

Then came AI, with its immense potential to enhance education — and facilitate cheating. That’s when Heuisler decided to ditch technology altogether in his classroom and return to the basics: pencil and paper. Tests, homework and in-class assignments are all on paper. The school already bans cell phones.

It’s more work for him, but worth it, he said.

“We want teenagers to think independently, voice their opinions, learn to think critically,” Heuisler said. “But if we give them a tool that allows them to not develop those skills, I’m not sure we’re actually helping them. Can you get by in life not knowing how to write, how to express yourself? I don’t know, but I hope not.”

AI and cognitive activity

Heuisler is not alone, according to research from the Center for Democracy and Technology. In a recent nationwide survey, the organization found that more than 70% of teachers say that because of AI, they have concerns about whether students’ work is actually their own. Nearly 75% of teachers say they worry students aren’t learning important skills like writing, research and reading comprehension.

The impact on students’ learning appears to be real, according to a recent study by the Massachusetts Institute of Technology. The study, “Your Brain on ChatGPT,” found that students who use AI for help writing essays showed significantly less cognitive activity than those who didn’t, and often couldn't remember details from essays they had just written. The essays themselves were also of poorer quality, with limited ideas, sentence structures and vocabulary compared to the essays written by students who didn’t rely on AI.

Nonetheless, about 85% of teachers and students use AI in the classroom, the Center for Democracy and Technology found. Teachers use it to organize lesson plans and grade papers, and students use it to do things like research and brainstorming.

Lack of consistent rules

But rules related to its use vary widely. The California Department of Education offers extensive guidance on how teachers can use AI in the classroom, but no strict requirements — even regarding students who use AI to cheat. One video urges teachers not to punish students caught using AI to write an essay. Instead, the video encourages teachers to come up with essay assignments that can’t be easily written by a machine, or require students to provide their notes and cite AI just like they would cite any other source for an essay.

Even within schools, teachers have different AI rules. Some encourage students to incorporate AI into their work, while others ban it outright. A recent survey by RAND research organization found only 34% of teachers said their school or district had consistent policies related to AI and cheating, and 80% of students said their teachers haven't provided guidance on how to use AI for schoolwork.

That confusion is the crux of the problem, said Alix Gallagher, a director at Policy Analysis for California Education who has studied AI use in schools. Because there are few clear rules about AI use, students and teachers tend to have “significantly” different views about what constitutes cheating, according to a recent report by the education nonprofit Project Tomorrow.

“Because adults aren’t clear, it’s actually not surprising that kids aren’t clear,” Gallagher said. “It’s adults’ responsibility to fix that, and if adults don’t get on the same page they will make it harder for kids who actually want to do the ‘right’ thing.”

Districts need to provide high-quality training for teachers and consistent policies for AI use in the classroom, so everyone knows what the rules are and teachers know how to navigate the new technology, she said.

Unsustainable?

In Hillary Freeman’s government class at Piedmont High School near Oakland, AI is all but forbidden. If students use AI to write a paper, they get a zero. She only allows students to use AI to summarize complex concepts, write practice questions for a self-assessment or when Freeman explicitly permits it for a specific task.

She appreciates that AI can sometimes be useful, but she worries that it’s too easy for students to use it as a crutch.

“Reasoning, logic, problem-solving, writing — these are skills that students need,” Freeman said. “I fear that we’re going to have a generation with huge cognitive gaps in critical thinking skills. … It’s really concerning to me. I want their futures to be bright.”

Detecting students’ use of AI is another obstacle, she said. It means spending time digging through version histories of students’ work, or using AI plagiarism screeners, which are sometimes inaccurate and more likely to flag English learners.

“It’s a huge ‘add’ to my job, and it doesn’t seem sustainable,” Freeman said.

Digital literacy and academic integrity

Google, meanwhile, so far has no plans to remove Lens from its Chrome browsers, even on school-issued laptops, although it is continuing to test various levels of accessibility. It recently paused a “homework help” Lens shortcut button, in response to feedback from users. 

The tech giant encourages students and teachers to learn more about positive and ethical uses of AI and how it can enhance learning. It’s also invested more than $40 million in AI literacy for students and teachers over the past few years.

“Students have told us they value tools that help them learn and understand things visually, so we have been running tests offering an easier way to access Lens while browsing,” said Google spokesman Craig Ewer. “We continue to work closely with educators and partners to improve the helpfulness of our tools that support the learning process.”

School administrators also have the option of disabling Lens on district-issued Chromebooks.

Los Angeles Unified has decided to keep Lens on its student laptops, at least for now, because the tool has plenty of positive uses that students should have the opportunity to explore the technology, a district spokesperson said.

But the district has instituted some guardrails: the tool is only available to students who have completed a lesson on digital literacy, and students and teachers must comply with the district’s academic integrity and responsible-use-of-technology rules. Those rules include bans on plagiarism and cheating.

“As new digital tools evolve, we continuously evaluate how they are used within our schools. When certain technologies or features may present concerns, we carefully analyze the risks, benefits, and overall impact on the learning environment,” a district spokesperson said.

This isn’t the district’s first challenge with AI technology. In 2024 Superintendent Alberto Carvalho unveiled a nearly $3 million chatbot called Ed, only to shelve it three months later when the company laid off half its staff.

Meanwhile, Stevenson said Lens vanished from his students’ Chromebooks last week after he alerted the district that some students were using it to cheat.

“It’s encouraging, but it also reveals how haphazard the introduction of AI has been,” Stevenson said. “Teachers and school leaders spend countless hours considering each detail of the learning experience, then Google totally undermines it with the click of a button. This isn’t how education is supposed to work.”

Data center builders don’t tell the public how much water they use, according to a new report — and the industry is encroaching into water-stressed and vulnerable communities.

The report, by the think tank Next10 and researchers at Santa Clara University, finds that planned data centers — the ganglia of artificial intelligence — are spreading to regions reliant on overtapped groundwater and strained surface water, with potentially major effects in the Central and Imperial Valleys.

But, reinforcing previous studies, the researchers found that a patchwork of state, federal and local policies allows data center operators to avoid publicly disclosing their actual water use.

California lawmakers tried to address this last year, but California Gov. Gavin Newsom vetoed the measure. Now, the legislature is trying again, with bills mandating disclosures about water use and planning.

“We have this huge build out, and we have very little data,” said Irina Raicu, who directs the Internet Ethics program at the Markkula Center for Applied Ethics at Santa Clara University.

Paired with California’s precarious water supplies, Raicu said, “It’s just not a good combination.”

Shaolei Ren, an expert on the environmental impacts of AI at UC Riverside who was not involved in the study, said the findings point to a much broader problem.

“Limited publicly available information about data center water use makes it difficult for communities, water providers and researchers to have meaningful public discussions and responsibly assess power-water trade-offs,” Ren said in an email.

Murky water use 

Few environmental impact reports for California’s data centers were publicly available online, the researchers found.

Raicu and co-author Iris Stewart-Frey, a professor of environmental science, went looking for the reports, meant to assess and disclose a project’s impacts for both nature and people under the landmark California Environmental Quality Act.

They found almost none. The ones they did find were largely for facilities in the city of Santa Clara.

Through interviews with planning officials, they discovered that projects can slip through with little environmental review if they fall under certain size or water use thresholds, or if they meet a city or county’s criteria for other approval pathways. These include something called ministerial approval, which requires planning agencies to approve a project that meets local zoning and other standards.

Even for data centers that undergo more stringent environmental scrutiny, the researchers found that documentation is rarely available to the public.

In the few cases the planning documents were posted publicly, the information — on the data center’s owner or operator, size, type of cooling system, the amount of water used, whether it’s recycled or potable — was often “missing, contradictory, or vague,” the report said.

The researchers said they contacted water providers in areas where data centers cluster, seeking usage data. None responded.

A shift to vulnerable regions

California’s data centers mostly cluster in the south San Francisco Bay Area and the city of Los Angeles, with smaller concentrations in Sacramento and San Diego.

But the report noted large, planned projects in rural and less affluent regions — like in Santa Clara County’s Gilroy, as well as in the heavily agricultural Imperial Valley.

“They need a bunch of cheap land,” Raicu. “If we’re not careful, they will end up being pitched, very convincingly, to communities that have real needs — without enough attention being paid to the water part.”

Khara Boender, director of state policy for the Data Center Coalition, which has opposed bills mandating more granular water-use reporting, said in an email the industry is “committed to being a good neighbor.”

Boender argues that data centers collectively “used significantly less water than other essential industries in 2025, including the agriculture, power, food and beverage, and semiconductor sectors,” but the coalition offers no data to back that up.

Collective use matters less than local impacts in a state where each community has its own mix of water supplies and strains, according to a previous study published by a team at UC Berkeley.

Whether data centers use a lot or a little water relative to agriculture or other industries, “what matters most is the scale of new local use compared to available local supply,” the Berkeley team concluded earlier this year. “Unfortunately, this picture is clouded by data deficiencies.”

In this week’s report, the Santa Clara University team drilled into those local supplies and community vulnerabilities to anticipated expansion.

“We’re at the brink of this happening in California,” Stewart-Frey, the environmental scientist, said. Her report, she added, isn’t advocating against data centers. But “communities should know what they’re getting themselves into.”

Debates over proposed data centers are erupting in a Kern County desert community with dwindling groundwater and in the hot Imperial Valley, which draws from the strained Colorado River. 

Monterey Park residents in the San Gabriel Valley successfully opposed one data center project over environmental concerns and inadequate information and secured an upcoming vote on a citywide ban.

In a letter to city officials, a representative for the developer dismissed opponents as “rage-baiting an uninformed mob to pressure your decisionmaking.”

Raicu pushed back. “If those communities are uninformed about the issue — whose fault is that? Who should be informing the people so that you don’t have this kind of pushback, if there is no need for it?”

New laws v. Big Tech

Last year, Assemblymember Diane Papan, a Democrat from San Mateo, authored a bill requiring data center operators to report estimated or actual water use to their water supplier when seeking or renewing a business license or permit.

Gov. Gavin Newsom vetoed the measure amid industry pressure, saying he was “reluctant to impose rigid reporting requirements about operational details on this sector without understanding the full impact on businesses and the consumers of their technology.”

Now, Papan is trying again with two bills. One largely reprises last year’s measure, with additional reporting required to the city and county. The other would bar local governments from approving new or expanded data centers unless the developer discloses information about their water use and plans.

It would also set other requirements — like prohibiting development in overdrafted groundwater basins in places like the San Joaquin Valley, unless state water managers OK it.

“You cannot manage what you have not and cannot measure,” Papan said. “The public likes transparency, and they should.”

Both bills cleared a key legislative chokepoint this week but face staunch opposition from the tech industry and business groups.

“If they run out of water, guess what happens? And they can’t cool their systems — are they going to succeed?” Papan said. “To which I say, help us help you.”

Nestled between Historic Filipinotown and Echo Park is a bookstore turned artisan craft space turned food market, all within 900 square feet. Every Sunday, A Good Used Book on Glendale Boulevard transforms from a retail bookstore into what they call “Sunday Funday Market.”

Founders Jenny Yang and Chris Capizzi spent seven years operating as a pop-up without a brick-and-mortar location. Opening their doors to local vendors pays homage to their own roots selling at Los Angeles markets, from the Melrose Trading Post to the Pasadena Rose Bowl Flea Market.

“Mega giant online sellers have the scale and the resources and the patience and the reach to capture most people,” Capizzi said. “Whereas for us, I think we have to be really creative — we have to band together.”

Yang and Capizzi’s long history of vending at markets taught them how isolating running a small business can be. At their market, they aim to build connections with each vendor and strategize the best timing and layout so everyone can succeed.

“[Amazon and Barnes & Noble] are Goliath, and we’re not even David — we’re just the ant underneath David’s foot,” Capizzi said. “I think we can do what we do and try to get as many people, at our level or even smaller, to get together.”

Weekly markets at A Good Used Book have captivated the neighborhood since its opening in October 2023, with charming names like “Sunday Funday,” “Saturday School” and “Hi-Fi Friday Night,” plus hand-drawn flyers by well-known artist Noah Harmon. Now, it’s become a weekly occurrence where LA pop-ups can display their own crafts, allowing local readers to indulge in a little more than a pocket paperback.

Each week holds a Pandora’s box of niche snacks, crafts or trinkets you didn’t know you needed, ranging from Southeast Asian-inspired trail mix to natural incense sticks to vintage Japanese audio equipment. One week you might be enticed to adopt a kitten from a rescue booth outside, another week you might impulsively get a stick-and-poke tattoo in the back of the store.

On one sunny Sunday afternoon, Brandon Stanciell hand-tossed fresh pizza dough on the sidewalk outside the bookstore. His 2-year-old pop-up, Pizza Ananda, which he named after his daughter, is an homage to her and to Italian cooking, a hobby he started during paternity leave. An hour before the market closed, Stanciell had already sold out and garnished his last pepperoni-and-hot-honey pie for one lucky customer.

“I love that places like this allow us all to meet at once to share what we have and give it to the community around us,” Stanciell said.

For the owners, building a community market is about deepening relationships with the people who walk through their doors. In an increasingly digital landscape, it is also a reciprocal partnership among local businesses.

“A lot of people talk about community building nowadays as a marketing strategy,” Capizzi said. “But I think the actual community building comes from talking to each vendor and each customer and being a consistent presence in the neighborhood.”

While customers browsed for unique titles, Gerin del Carmen worked her booth of ceramic dishware, oyster-shaped trinket holders and vases resembling miniature boxes. As a ceramicist, del Carmen draws from her Filipino heritage, including the Balikbayan boxes that represent immigrants sending gifts to family in the Philippines.

“Sharing the community and your space is such a big deal. This is not a huge, gigantic Barnes & Noble store,” del Carmen said. “It has so much foot traffic, and the fact that [the owners] are setting up and sharing the space once or twice a week with other vendors and other artists is huge.”

Yang and Capizzi may think of themselves as an “ant underneath David’s foot,” but A Good Used Book is building a colony of vendors, rooted in community.

Whether you and your friends are looking for a brunch spot to cater to everyone's palates, or taking a trip to the historic Grand Central Market, food halls make for an easy, affordable place to satisfy cravings — especially in SoCal, where diverse selections of dishes reign supreme.

But these spaces fill a void much deeper than our appetites. They bring new life to old storefronts, factories or even airfields (see list below), and can offer a way to keep dollars within the community by becoming a hub for local businesses.

With that said, here's a short list of food halls where you'll get more than just a killer meal.
