Looking for new posts…
Indeed, it has been quite a week, so I thought I'd share it with the KDD 2026 audience! For my Google colleagues who might have sent me internal chat messages after I closed my laptop for a final time on Thursday afternoon, I apologize for my lack of response!

@JeffDean @CMantseris Waymo never really had a chance against Tesla. This will be obvious in hindsight.

@CMantseris Tesla did report in April that they have accumulated 50,000 miles driving cars from the end of the factory line to the outbound logistics lot in their factories in TX and CA.

@JeffDean @CMantseris Wrong (huge fan and you are the GOAT). Have a Tesla with hardware 4. 95% of my drives are autonomous miles. Its magical. I am sure you have tested the latest FSD release :)

@CMantseris I don't think Tesla has anywhere near the volume of rider-only autonomous miles that Waymo has (96M for Waymo, as of today). The safety data is quite compelling for Waymo, as well.

@JeffDean I would be interested to see your arguments compared to Tesla who also claim to be the most advanced large scale application of embodied AI.

Giga Texas production now uses FSD Unsupervised to deliver cars from end of line to the outbound logistics lot.
Over 50,000 driverless miles have been accrued between California and Texas factories so far https://t.co/79zKY0U6Ox

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. https://t.co/cRSMiFfwAP
