BurnBot RX burns unwanted vegetation without emitting plumes of smoke.

Last year’s record heat wave worsened drought and dry conditions across the globe, a particularly calamitous situation for California, which has seen 13 of the state’s 20 most destructive wildfires in history break out since 2017.

In South San Francisco, a small startup is working on a high-tech approach to wildfire prevention.

Anukool Lakhina and Waleed “Lee” Haddad founded BurnBot in 2022 to develop robotics and remote-controlled vehicles that can munch up and burn away invasive plants or other dry vegetation that can fuel fires if left fallow.

BurnBot has just raised a $20 million funding round led by climate-focused ReGen Ventures, for expansion, hiring, and to develop new machines that can traverse steeper hills and get into tighter spaces.

Before BurnBot, firefighters and land owners had to use expensive, time-consuming and more dangerous options like grazing away the vegetation (typically with goats), burning it, applying herbicides or removing vegetation mechanically with a mix of equipment and manual labor.

“The sort of traditional way to do a prescribed burn is with drip torches, and that requires a large number of people,” said Lakhina, BurnBot’s CEO. “A drip torch is like a diesel watering can. You go around, you drop diesel, then ignite it.”

Burnbot’s current model, the RX, is a remote-operated vehicle that looks a cross between an oversized Zamboni and a steel cooking range with a set of fire extinguishers strapped to its back. Like other agricultural and construction equipment, the RX rolls forward on tank-like tracks and wheels, which enable it to maneuver through rough fields.

Within the chambers of the RX are several rows of torches that emit blue flames, and adjust the heat levels precisely to zap away unwanted vegetation or other fuels on the ground below. The chambers of the BurnBot RX also trap and torch away the smoke that comes from burning vegetation, so it doesn’t pollute the air in surrounding communities. When the torching is done, the RX sprays water repeatedly to extinguish any remaining embers.

Lakhina said BurnBot’s systems can be put to use where traditional controlled burns won’t work. For example, drip torch burns produce a good deal of smoke, which is conductive enough it would interfere with the proper functioning of power lines or high-voltage equipment. BurnBot’s machines can be used even under power lines.

The company is aiming to make every person who works in fire prevention 10 times more effective than they were with old methods, Lakhina said.

Haddad, BurnBot’s chief technology officer, noted that land isn’t always ready to “receive fire” in a prescribed burn. So the company has programmed equipment, which it procures from another supplier, to roll ahead of the RX to crunch up the vegetation in an area of concern before it’s ready for torching.

BurnBot plans to conduct a prescribed burn this Friday in San Diego, a project for CalTrans, the state’s transportation agency. It also plans for another burn for Pacific Gas & Electric, the state’s major utility, in June.

PG&E spends upward of $1 billion on “vegetation management” each year. Kevin Johnson, who leads the company’s Wildfire Resilience Partnerships, said PG&E is always “looking for opportunities to do this work safer, faster, cheaper and to be more environmentally friendly.”  

BurnBot has already completed one demonstration of its controlled burn machine underneath PG&E transmission lines.

Brice Muenzer, a battalion chief with CalFire in Monterey, California, said massive fires in the state and throughout the U.S. over the past decade have been partly caused and certainly exacerbated by overzealous elimination of smaller fires, including ritual fires from indigenous communities.

“We removed fire from the ecosystem for the last 150 years and are living through that reality now,” the chief said.

CalFire has worked with BurnBot personnel, machines and additional drones overhead, to create what’s known as a control line in the field in at least one location. Muenzer says the group hopes to do more with the startup.

Creating a control line, or blacklining the land, involves firefighters strategically burning areas when the weather is calm and where flames can be controlled to create scars that will block other fires from jumping in and reaching areas with lots of new material to burn.

BurnBot aims to eventually expand its operations beyond California, with offices and fleets of its machines wherever vegetation management is needed and wildfire risk is highest.

“There are 50 million acres that the U.S. Forest Service has said need treatment every year and that’s just forest land,” said Lakhina. In the U.S. there are 237 million acres that need treatment overall. And grazing can cost $1,000 an acre.”

Childrens’ health is at stake along with property and healthy forests, Lakhina added. According to the Harvard School of Public Health, wildfire smoke can be more toxic than air pollution from other sources, leading to more emergency room visits, especially for children who are exposed.

Because BurnBot offers greater precision than grazing, herbicides and mechanical removal, its systems should prove ecologically more beneficial as well, Haddad said. The BurnBot RX is able to help prevent the spread of seeds from invasive species, for example, without causing any of those species to develop resistance to an herbicide.

ReGen was joined in BurnBot’s funding round by investors including AmFam Ventures, which is the venture arm of an insurance company, Toyota Ventures, and earlier backers including robotics fund Pathbreaker, Convective Capital and Chris Sacca’s Lowercarbon Capital.

Workday shares sink on subscription revenue guidance concerns

Shares of software maker Workday dropped as much as 10% on Wednesday as analysts lowered their price targets, citing a lack of a upside after the company revised its full-year subscription revenue forecast.

Many software stocks have been under pressure in 2025 as commentators have worried that generative artificial intelligence tools that can quickly write lines of code might pose risks to incumbents.

This year, Workday has announced the launch of several AI agents and expanded its offerings through startup acquisitions. Earlier this month, Workday completed the $1.1 billion purchase of AI and learning software company Sana.

Despite those moves, Workday’s third-quarter earnings report on Tuesday failed to impress Wall Street.

The company called for $8.83 billion in subscription revenue for the fiscal year that will end in January 2026, implying 14.4% growth, but the figure was up just $13 million from the company’s guidance in August. The new number includes contributions from Sana and a contract with the U.S. Defense Intelligence Agency, Workday finance chief Zane Rowe told analysts on a conference call.

“Investors were likely looking for more of a beat-and-raise quarter,” Cantor Fitzgerald analysts Matt VanVliet and Mason Marion wrote in a note to clients. They have the equivalent of a buy rating on Workday stock. The new number, they wrote, “borders on a slight guide down.” The analysts held their 12-month price target on Workday stock at $280.

Stifel, with a hold rating on the stock, lowered its Workday target to $235 from $255.

“It does not appear that the underlying momentum of the business is showing any signs of stabilization,” Stifel’s Brad Reback and Robert Galvin wrote in a note.

Reback and Galvin said Workday implied that growth from its 12-month subscription revenue backlog will continue to slow when removing impact from acquisitions. They expect the trend to continue even as customers sign up for Workday’s AI products, they wrote.

The outcome was “like turkey without the gravy,” Evercore analysts, with the equivalent of a buy rating on the stock, wrote in the title of their note.

Analysts at RBC, which also has the equivalent of a buy rating on Workday shares, lowered their price target to $320 from $340. Despite the mixed guidance, they wrote in a note to clients, results for the fiscal third quarter did exceed consensus. Plus, AI products contributed over 1.5 percentage points of annualized revenue growth, Workday CEO Carl Eschenbach said on Tuesday’s conference call.

‘”We remain encouraged by early AI momentum,” the RBC analysts wrote.

MIT study finds AI can already replace 11.7% of U.S. workforce

MIT study finds AI can already replace 11.7% of U.S. workforce

AI can already replace 11.7% of the U.S. workforce, MIT study finds

Massachusetts Institute of Technology on Wednesday released a study that found that artificial intelligence can already replace 11.7% of the U.S. labor market, or as much as $1.2 trillion in wages across finance, health care and professional services.

The study was conducted using a labor simulation tool called the Iceberg Index, which was created by MIT and Oak Ridge National Laboratory. The index simulates how 151 million U.S. workers interact across the country and how they are affected by AI and corresponding policy.

The Iceberg Index, which was announced earlier this year, offers a forward-looking view of how AI may reshape the labor market, not just in coastal tech hubs but across every state in the country. For lawmakers preparing billion-dollar reskilling and training investments, the index offers a detailed map of where disruption is forming down to the zip code.

“Basically, we are creating a digital twin for the U.S. labor market,” said Prasanna Balaprakash, ORNL director and co-leader of the research. ORNL is a Department of Energy research center in eastern Tennessee, home to the Frontier supercomputer, which powers many large-scale modeling efforts.

The index runs population-level experiments, revealing how AI reshapes tasks, skills and labor flows long before those changes show up in the real economy, Balaprakash said.

The index treats the 151 million workers as individual agents, each tagged with skills, tasks, occupation and location. It maps more than 32,000 skills across 923 occupations in 3,000 counties, then measures where current AI systems can already perform those skills.

What the researchers found is that the visible tip of the iceberg — the layoffs and role shifts in tech, computing and information technology — represents just 2.2% of total wage exposure, or about $211 billion. Beneath the surface lies the total exposure, the $1.2 trillion in wages, and that includes routine functions in human resources, logistics, finance, and office administration. Those are areas sometimes overlooked in automation forecasts.

The index is not a prediction engine about exactly when or where jobs will be lost, the researchers said. Instead, it’s meant to give a skills-centered snapshot of what today’s AI systems can already do, and give policymakers a structured way to explore what-if scenarios before they commit real money and legislation.

The researchers partnered with state governments to run proactive simulations. Tennessee, North Carolina and Utah helped validate the model using their own labor data and have begun building policy scenarios using the platform.

Tennessee moved first, citing the Iceberg Index in its official AI Workforce Action Plan released this month. Utah state leaders are preparing to release a similar report based on Iceberg’s modeling.

North Carolina state Sen. DeAndrea Salvador, who has worked closely with MIT on the project, said what drew her to the research is how it surfaces effects that traditional tools miss. She added that one of the most useful features is the ability to drill down to local detail.

“One of the things that you can go down to is county-specific data to essentially say, within a certain census block, here are the skills that is currently happening now and then matching those skills with what are the likelihood of them being automated or augmented, and what could that mean in terms of the shifts in the state’s GDP in that area, but also in employment,” she said.

Salvador said that kind of simulation work is especially valuable as states stand up overlapping AI task forces and working groups.

The Iceberg Index also challenges a common assumption about AI risk — that it will stay confined to tech roles in coastal hubs. The index’s simulations show exposed occupations spread across all 50 states, including inland and rural regions that are often left out of the AI conversation.

To address that gap, the Iceberg team has built an interactive simulation environment that allows states to experiment with different policy levers — from shifting workforce dollars and tweaking training programs to exploring how changes in technology adoption might affect local employment and gross domestic product.

“Project Iceberg enables policymakers and business leaders to identify exposure hotspots, prioritize training and infrastructure investments, and test interventions before committing billions to implementation,” the report says.

Balaprakash, who also serves on the Tennessee Artificial Intelligence Advisory Council, shared state-specific findings with the governor’s team and the state’s AI director. He said many of Tennessee’s core sectors — health care, nuclear energy, manufacturing and transportation — still depend heavily on physical work, which offers some insulation from purely digital automation. The question, he said, is how to use new technologies such as robotics and AI assistants to strengthen those industries rather than hollow them out.

For now, the team is positioning Iceberg not as a finished product but as a sandbox that states can use to prepare for AI’s impact on their workforces.

“It is really aimed towards getting in and starting to try out different scenarios,” Salvador said.
