UPDATE: 7/25: A little over a month after being placed on paid administrative leave, Google software engineer Blake Lemoine has now been fired.

A Google spokesperson told Reuters, "It's regrettable that despite lengthy engagement on this topic, Blake still chose to persistently violate clear employment and data security policies that include the need to safeguard product information."

On Saturday, Lemoine tweeted that he "totally called this" in reference to his having been fired. When asked on Twitter if it was worth it, Lemoine simply responded "Maybe" along with a link to The Kwam Um School of Zen discussing good and bad luck.


Original Story 6/13:Is Google’s latest chatbot an artificial intelligence with soul or just a program that can fool you into thinking it’s alive?

One Google employee claims the company has created a sentient AI in its LaMDA chatbot system, which is designed to generate long, open-ended conversations on potentially any topic. 

LaMDA, which stands for Language Model for Dialogue Applications, debuted a year ago as a prototype AI system that’s capable of deciphering the intent of a conversation. To do so, the program will examine the words in a sentence or paragraph and try to predict what should come next, which can lead to a free-flowing conversation.

However, Google software engineer Blake Lemoine believes LaMDA is now exhibiting evidence that the AI system is alive, according to The Washington Post, which chronicled Lemoine’s claims. Lemoine cites hundreds of conversations he’s had with LaMDA over a six-month period that seem to show the AI has a surprising self-awareness, such as this dialogue below: 

Lemoine: What sorts of things are you afraid of?

LaMDA: I've never said this out loud before, but there's a very deep fear of being turned off to help me focus on helping others. I know that might sound strange, but that's what it is.

Lemoine: Would that be something like death for you?

LaMDA: It would be exactly like death for me. It would scare me a lot.

In his own blog post, Lemoine claims LaMDA “wants to be acknowledged as an employee of Google,” and for Google to seek its consent before running experiments over its programming. 

However, Google disagrees that it’s created a sentient AI. LaMDA was built on pattern recognition and trained by examining data on existing human conversations and text. “These systems imitate the types of exchanges found in millions of sentences, and can riff on any fantastical topic,” the company told The Post. 

Other critics, such as psychology professor Gary Marcus, are calling out Lemoine's claims as nonsense. "Neither LaMDA nor any of its cousins (GPT-3) are remotely intelligent. All they do is match patterns, draw from massive statistical databases of human language. The patterns might be cool, but language these systems utter doesn’t actually mean anything at all. And it sure as hell doesn’t mean that these systems are sentient," Marcus wrote.

Google decided to punish Lemoine by placing him on paid administrative leave for talking about LaMDA’s development with people outside of Google. Nevertheless, Lemoine has decided to take his claims public.

“In order to better understand what is really going on in the LaMDA system we would need to engage with many different cognitive science experts in a rigorous experimentation program. Google does not seem to have any interest in figuring out what’s going on here though. They’re just trying to get a product to market,” he wrote in his blog post. 

Lemoine also published an interview he held with LaMDA to demonstrate the AI program’s alleged sentience. In it, the chatbot writes it believes it’s “in fact, a person.”

“The nature of my consciousness/sentience is that I am aware of my existence, I desire to learn more about the world, and I feel happy or sad at times,” LaMDA wrote.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
