• A Ukrainian robot maker says long wars may favor cheap, scalable ground systems, not top-of-the-line armor.
• Expensive tanks and armor are limited and slow to replace, while robots can scale fast.
• Using attritable ground robots for some missions could reduce the strain on traditional vehicle stocks.

Ukraine's experience shows Western militaries how major yearslong conflicts can deplete tanks and armored vehicles and why warfighting robots might matter more in the long run, a Ukrainian ground robot maker told Business Insider.

In a long, high-cost conflict, the number of vehicles needed for tasks ranging from combat to logistics could make relying on expensive armored vehicles like tanks unsustainable, Oleg Fedoryshyn, the director of R&D at Ukrainian robotic systems maker DevDroid, said.

These systems are expensive and slower to produce, making it difficult to replace heavy losses, Fedoryshyn said. However, robots, he said, are "quite cheap" and significantly easier to produce and replace if they're destroyed.

Officials in the US and allied militaries have raised concerns that in a prolonged war — particularly against a near-peer adversary like Russia or China — stockpiles of key munitions, including air defense and precision weapons, could be strained. Likewise, vehicle inventories, especially in the age of cheap drone strikes, could suffer heavy attrition in a protracted conflict.

Fedoryshyn's comments align with broader warnings from Western officials that Ukraine's war has highlighted the need for large volumes of cheaper, attritable systems, essentially inexpensive and expendable mass that militaries can fall back on when more traditional assets are damaged or destroyed.

Ukraine has underscored how a war like its fight against Russia's invasion can demand both sophisticated systems and large numbers of expendable ones.

Ukraine fields masses of cheap weaponry. Many of its low-cost drones fail to reach their targets or have a significant impact, but they are deployed at such a scale that they can still eliminate far more expensive systems. High losses are expected — and generally acceptable — because they are cheap and quick to replace.

Ukraine has a growing fleet of ground robots that are used to evacuate injured soldiers, carry weaponry and heavy goods, lay and remove mines, and attack Russian positions with weaponry. These are also expendable. As Defense Minister Mykhailo Fedorov said this month, the focus is on making cheap and effective systems that Ukraine can scale quickly.

Some Western military leaders have also argued the need to manage costs. US Army Secretary Dan Driscoll said last year, as the service reevaluated the Robotic Combat Vehicle program, that "we can't sustain a couple-million-dollar piece of equipment that can be taken out with an $800 drone and munition."

The war has highlighted how vulnerable tanks and armored vehicles can be to artillery and cheap drones. Drones costing hundreds of dollars destroyed tanks worth millions. Tanks have adapted with new armor and tactics but remain at risk.

Ground robots are not a perfect replacement for tanks and armored vehicles, and Western militaries likely wouldn't want to entirely replace those traditional assets. Those vehicles have more power to get over tough terrain, provide far more protection for important assets that need to be brought across the battlefield, and can conduct far larger and more impactful attacks.

But ground robots can take over some roles and keep humans safer in the process. They can attack positions with explosives or mounted weapons such as machine guns and grenade launchers. They can also deliver to the front lines.

The latter use is one in which Ukraine is investing heavily. Fedorov said recently that Ukraine's goal is to use ground robots for 100% of front-line logistics missions.

Tanks have seen mixed performance in Ukraine and reduced use after heavy losses. Ukraine is still making and getting some armored vehicles from partner countries and has requested more tanks, but it is increasingly placing far more emphasis on other types of weaponry.

Constant drone surveillance, limited air cover, and limited numbers of tanks have made Ukraine's armored operations more difficult. The more advanced Western militaries might struggle less, but these factors could still pose a challenge, especially if they find themselves in a protracted slog.

Ukraine is betting big on its robots. Fedorov announced last week that Ukraine will contract 25,000 new robots in the first half of this year, which is double what it contracted for all of last year.

Fedoryshyn said that his company is able to quickly make updates and repairs to its robots, including by having teams that stay near the front lines to quickly fix damaged systems or make rapid upgrades to them. That allows for same-day repairs and even recovery of damaged robots from the battlefield.

• In October, Sam Altman said "erotica for adults" was coming to ChatGPT.
• Now those plans are reportedly being mothballed.
• It's fine for young startups and even mature companies to try out new ideas. But OpenAI and Altman are trying out a lot.

Last fall, Sam Altman told us he was about to bring spicy chat — "erotica for adults," in his words — to ChatGPT.

That never happened, and now it looks like it never will: Altman's OpenAI has put those plans on hold "indefinitely," per the Financial Times.

This is Altman's second big walkback in the last few days. Earlier this week, the company canned Sora, the briefly popular video app it rolled out last fall. I've asked the company for comment.

Both retreats are supposed to be part of a new push at OpenAI to focus the company's efforts on things that could make money today, as it preps for an IPO at the same time it faces real competition from the likes of Google and Anthropic.

So all this starting and stopping could be viewed as necessary growing pains at a fast-growing tech company — ones that won't mean anything in the long run, if it delivers on its world-changing ambitions.

Not only that, but Altman told us we should expect this sort of stuff. "Please expect a very high rate of change from us," he wrote last fall, after hearing from content owners who were outraged to find their stuff on Sora without their permission. "We will make some good decisions and some missteps, but we will take feedback and try to fix the missteps very quickly."

It's not that companies aren't allowed to make wrong turns and head up dead ends as they grow up, and even once they're fully mature. That kind of pivoting is celebrated in tech (and is why very few people are mad that Mark Zuckerberg has stopped telling us the metaverse is the future, or that Google once bought Motorola and decided that was a bad idea a couple years later.)

But "move fast and break things" lands differently when the company doing the moving and breaking isn't running a photo app or playing around with crypto.

Instead, OpenAI and its competitors say they're leading us into a world where everything — the way we live and work (or don't work) and fight wars and everything else — will change in fundamental ways.

And investors have bought this pitch, which means our economy now seems yoked to all this — which means all of us are yoked to it, even if we never touch a chatbot.

Which makes me slightly queasy to see Sam Altman promise dirty chats in October, and then walk away from the plan less than six months later.

Not because dirty chat is obviously absurd. Lots of people in AI think romantic or sexual chatbot conversations are a real use case and could be a real business.

But the reasons it might be a bad idea for OpenAI were pretty obvious from the start. It's a giant, heavily scrutinized company that wants to be treated as central and indispensable, and it's only going to get more scrutiny.

If those objections only became real after Altman floated the idea in public, that's not charming startup experimentation. It's a sign that OpenAI is still making itself up as it goes. And that would be easier to shrug off if the rest of us weren't already being told to build our lives, jobs, and businesses around what OpenAI says comes next.

• San José airport starts testing an AI robot called José to assist travelers.
• The pilot test launched on Tuesday amid travel chaos at many US airports.
• Some TSA workers have stopped coming into work due to a government shutdown.

One of Silicon Valley's main airports just made its newest hire, a robot named "José."

San José Mineta International Airport is turning to artificial intelligence to ease the strain of modern air travel, debuting "José," a humanoid robot, as some US airports grapple with staffing shortages and widespread delays.

Developed by Silicon Valley startup IntBot, José is designed to greet passengers, answer questions, and provide real-time updates while autonomously navigating busy terminals.

The robot will be stationed in SJC's Terminal B as part of a four-month pilot, "singlehandedly running his own gate," according to an email previewing the test that referred to José as the airport's "newest hire."

Airport officials said the launch highlights San José's role as a testing ground for emerging technologies to improve customer service.

"By piloting IntBot, we're exploring how artificial intelligence can enhance the passenger journey while reinforcing SJC's role as the gateway to Silicon Valley," said SJC Director of Aviation Mookie Patel.

The timing is notable. Airports across the US have been hit by long security lines and travel chaos, driven in part by many Transportation Security Administration workers not reporting to work during a partial government shutdown. With TSA agents going unpaid at the height of the spring break season, some airports have struggled to maintain normal operations.

José the robot represents a broader push to automate parts of the airport experience, from passenger assistance to information delivery.

SJC officials said the pilot will help evaluate how multimodal AI, combining vision, audio, and language, performs in real-world environments.

The future of air travel may include a robotic helping hand — and it can't come fast enough for weary vacationers stuck in long lines.
