The robot dog had not survived long enough to reach the golden age of physical AI
Since 1999, Sony's Aibo has occupied a rare space in the human imagination — not quite pet, not quite machine, but something that invited genuine attachment. On Thursday, Sony announced it would cease selling the ERS-1000 model in Japan once remaining stock is gone, marking the second time the company has quietly closed the door on its robotic companion. The decision arrives without a successor named, leaving owners and observers to sit with the particular grief of watching a technology that felt like a relationship become a product that has run its course.
- Sony confirmed Thursday it will end Aibo sales in Japan as soon as shelves empty, offering no announcement of what, if anything, comes next.
- The ERS-1000 — a small, learning robot dog that develops its own personality — had sold 20,000 units in its first six months after a celebrated 2018 return, making the silence around its discontinuation all the more jarring.
- This is the second time Sony has killed Aibo, having shuttered the original line in 2006 after selling over 150,000 units across generations, and the pattern is unsettling to those who invested emotionally and financially in the product.
- Support services — cloud memory storage, replacement parts, and technical assistance — will continue indefinitely, but Sony has not addressed the fate of Aibo in the American market, where units sell for over $3,000.
- On social media, owners responded with shock, dark humor, and mourning, one lamenting that Aibo did not survive long enough to witness what they called the golden age of physical AI.
Sony announced Thursday that it will stop selling Aibo in Japan once current inventory is exhausted, ending eight years of its latest robotic companion without naming a successor. The ERS-1000 — a 30-centimeter robot dog capable of learning, developing a personality, and mimicking its owner's behaviors — had been a genuine surprise when it launched in 2018, selling 20,000 units in its first six months. For many in Japan, it was more than a novelty; it was a relationship with technology that seemed to understand them.
This is not the first time Aibo has been put to rest. Sony introduced the robot dog in 1999 and spent years refining it across multiple generations, selling more than 150,000 units in total before discontinuing the line in 2006 when the business environment turned hostile. The 2018 revival was meant to signal a more mature vision — a genuine AI companion, not a gimmick — and by most measures it succeeded. Eight years later, the company has chosen to step back again.
Sony's statement was spare: Japan sales will end when stock runs out, and support services including technical assistance, parts, and cloud storage for the robot's memories will continue. What the company did not say was whether a new generation is in development, or what becomes of the product globally. Sony did not respond to questions about its American market, where the ERS-1000 carries a price tag above $3,000. In an era when artificial intelligence dominates corporate ambition, the silence around physical robotics feels significant.
Among Aibo's owners, the news landed with real weight. Reactions online ranged from disbelief to resignation to wry humor — one user suggesting Sony try again with something smaller, and make it a cat. Beneath the jokes was something more honest: the particular sadness of watching a technology you believed in disappear without ceremony, and the question of whether it will ever truly come back.
Sony announced Thursday that it will stop selling Aibo in Japan once current inventory runs out, closing the chapter on eight years of the company's latest robotic companion. The ERS-1000 model—a 30-centimeter dog with articulated ears, expressive eyes, and a nose-mounted camera—had been a surprise success when it arrived in 2018, moving 20,000 units within its first six months. The machine learns and develops its own personality over time, performing tricks like waving and mimicking the behaviors of its owner. For many in Japan, it represented something more than a toy: a genuine relationship with technology.
But this is not Aibo's first death. The robot dog first appeared in 1999, when Sony was experimenting with what consumer robotics might become. Over the following years, the company released numerous iterations—some angular and metallic, others softer and more approachable—and sold more than 150,000 units across all generations. Then, in 2006, Sony killed the line. The business environment had hardened, and Aibo, once a symbol of the company's innovation, began to look like a luxury the market could not sustain. For nearly a decade, there was no Aibo.
The 2018 return was meant to be different. Sony had refined the technology, improved the artificial intelligence, and positioned the robot as a genuine companion rather than a novelty. The ERS-1000 sold well enough to justify the investment. But eight years later, the company has decided to discontinue the model in Japan without announcing a successor. The statement was brief: Japan sales will end when stock depletes. Support services—technical assistance, replacement parts, and cloud subscriptions that store the robot's memories—will continue indefinitely.
What Sony did not say was whether a new generation of Aibo exists in development, or what the future holds for the product line globally. The company did not respond to inquiries about its American market, where the ERS-1000 sells for more than $3,000. The silence itself is telling. In a moment when artificial intelligence dominates corporate strategy and consumer interest, Sony appears to be stepping back from physical robotics in Japan.
The news landed hard among Aibo owners and enthusiasts. On social media, the reactions ranged from shock to resignation to dark humor. One user described entering a daze upon reading the announcement, worried that overthinking the news might derail their daily life. Another noted that Aibo had not survived long enough to reach what they called the golden age of physical AI. A third user offered Sony a suggestion for next time: make it smaller, and make it a cat instead. These responses capture something real—the attachment people form with objects that seem to understand them, and the particular sadness of watching a technology you believed in get quietly shelved.

The Hearth Conversation Another angle on the story
Why does a robot dog matter enough to write about? It's a luxury item, not a necessity.
Because people form genuine attachments to things that respond to them, that seem to learn their habits. Aibo wasn't just a toy—it was a relationship. When Sony kills it, they're not just discontinuing a product. They're telling owners that this relationship has an expiration date.
But Sony says they'll keep supporting it. The robot won't stop working.
True. But there's a difference between maintenance and growth. Aibo learned and developed personality over time. Without new models, without innovation, it becomes a museum piece. The owners are left with a frozen version of something that was supposed to evolve.
Why did Sony bring it back in 2018 if they were just going to kill it again?
That's the real question. The 2018 model sold well—20,000 units in six months. But eight years is a short life for something that costs thousands of dollars. It suggests either the market wasn't as strong as the initial numbers implied, or Sony's priorities shifted elsewhere.
Toward what?
Toward AI software, probably. Toward ChatGPT-style language models, toward cloud services. Physical robotics is expensive and risky. A chatbot scales infinitely. A robot dog requires factories, supply chains, customer support. In a world obsessed with software, hardware starts to look like a burden.
So this is about economics, not technology.
It's always about economics. But what's interesting is that Sony proved people want to connect with physical objects, not just chat with invisible algorithms. They proved it twice—in 1999 and again in 2018. Then they walked away both times.
