In April, '17, @jsomers of @NewYorker reached out & said he wanted to do a small profile of me & my longtime colleague Sanjay Ghemawat, watch us work for a few hours, maybe dinner, etc.
It came out today. I think it captures our working style really well. newyorker.com/magazine/2018/…

Here's a nice @GeekWire article by @ToddBishop about the graduation, including a few more snippets of what I said in my talk.

People replace their phones every ~4 yrs. This means there are hundreds of millions of old phones discarded each year that are still perfectly usable as computing devices. @Google in collabration with @UCSD is exploring how to turn these old phones into cloud-computing “phone clusters”. Putting phones back in service in this way can directly reduce the environmental footprint of computing by avoiding the need for further raw material extraction, and taking advantage of the embodied carbon already incurred from manufacturing these devices, and modern phones actually are already quite powerful computers.

Today on the blog, we discuss a pathway for the second life of phones through the exploration of “phone cluster computing”, which can directly reduce the environmental footprint of computing by avoiding the need for further raw material extraction. More →goo.gle/4aJe5vO

Quite interesting thread on capabilities of real biological neurons (spoiler: they're way more capable than classical artificial neurons in a perceptron) . Nice work @IdoAizenbud and collaborators!
Jun 11
What can a neuron compute?
Real biological neurons are complex, but how capable are they?
Using a new method, we found that a single cortical neuron can classify cats vs dogs, recognize spoken words, and solve 10-bit parity, all tasks thought to require entire networks. (1/15)

For medical information, general AI frontier models (Google, OpenAI, Anthropic) outperformed specialized @EvidenceOpen and @UpToDate as assessed by 12 US clinicians, randomized and blinded to which model and extensive testing/benchmarks. This was not anticipated. @NatureMedicine

Denying entry to a Somali soccer official selected as one of the World Cup referees is quite shameful. The whole point of the World Cup is as a spirited athletic competition that brings us together, and allowing him to officiate is obviously the right thing to do.
Somali referee Omar Artan, who was set to be the first from his country to officiate at the World Cup finals, has been denied entry to the United States.

Speech translation has been one of the longest-running ML efforts at Google, and we’ve come a long way. Gemini 3.5 Live Translate is our latest speech-to-speech model, supporting 70 languages. It enables more natural conversations across languages in everyday products and apps.
Here’s an example of how partners at @InsideGrab are helping connect travelers with drivers. 🚗
Rolling out in Google Translate and via the Live API in @GoogleAIStudio.

This is not simply a new pancreatic cancer drug.
It is a reminder that even “undruggable” biology can become treatable with persistence.
Daraxonrasib doubled median OS vs chemotherapy in RAS G12 metastatic pancreatic cancer: 13.2 vs 6.6 months.
A remarkable ASCO moment.

Thanks for a great @twominutepapers conversation, Károly!
It was really fun to chat with the legendary @JeffDean. I asked him about things that only he may know the answer to. 🙂 Link to full video in thread.

This would be a huge blow to America's tech sector. This country has always benefited from attracting the world's best and brightest. We should be making that easier, not harder.

Most green-card applicants will need to go abroad to apply for permanent residency at an American consulate, rather than filing from within the U.S. as they do now, the Trump administration announced Friday. on.wsj.com/4v2Fqkr

Gemini 3.5 Flash is amazing!
- Performs better than 3.1 Pro on coding & agentic tasks
- 4x faster than other frontier models
- 12x faster in @antigravity - 800 tokens/sec!
- Often at less than half the cost
And Pro to come…
Try it in @antigravity, @GeminiApp & more - enjoy!

Four questions in under 2 minutes. Thanks to Google's social team for suggesting this little interlude at #googleio yesterday!
4 questions with @JeffDean (Chief Scientist, Google and one of the authors of the famous "cat paper" about unsupervised learning and neural networks in 2012) in under 2 minutes at #GoogleIO:
