Levels of Self-Driving Explained in a Real Waymo Ride
About the video: Soundarya and I set out to compare San Francisco’s two robotaxis: Waymo (Google) and Zoox (Amazon). Waymo showed up in a few minutes. Zoox? “It’s busy.” All afternoon. And every time since.So this became a full Waymo review instead. We rated it on availability, comfort, fear and price, explained the six levels of self-driving in a real ride, looked back at the night Waymos froze during the SF blackout, and fact-checked a 2012 Sergey Brin prediction. At the end, I found a way to actually get into a Zoox, which is coming in Part 2.Our Waymo ride: Civic Center to the Panhandle, 2.16 miles, 13 minutes, $15.30. Final scorecard:Availability: Waymo 9/10 · Zoox 0/10Comfort: Waymo 9/10 · Zoox, not rated until we ride itFear: Waymo 7/10 (autoplay song, no seatbelt reminder)Price: Waymo 2/10 · Zoox 10/10 (free… if you can get one)With Soundarya, author.Chapters:0:00 Trailer0:42 Waymo vs Zoox in San Francisco0:54 Google vs Amazon: quick context1:08 Our review criteria1:26 Waymo arrives in 30 seconds1:42 Getting in (and a surprise Tamil song)2:04 Fear, autoplay and no seatbelt reminder2:52 Ride comfort (and a Bose fact check)4:05 We miss Uber drivers4:38 The 6 levels of self-driving5:31 Why is there still a steering wheel?

I Let Grok Order My Food. It Picked... This.
So here is what I did. I let GrokBot order my food on Uber Eats, and I didnt tell it the restaurant or even the cuisine. My only rules: keep it under $50, and tip the driver $5, but only if a human delivers it. If a robot shows up, no tip 🤖Grokbot then signed in to Uber Eats, handled the verification, checked out at $44.77, and even offered to set up a surprise breakfast for me every friday, lol I took it. And yes, the friday breakfast actually showed up, it's in this video too. Follow me on Instagram for whatever it orders next🍜 the food was truly good, both times. Nobody paid me to say this. Im sharing the links only because I would order from these places again, and local restaurants deserve the shout out:Kung Fu Dim Sum, Fremont: https://www.kungfudimsumusa.comBill's Cafe, Fremont: https://www.billscafe.com⏱️ Chapters0:00 Trailer0:36 I'm letting an AI order my food0:50 The rules: no cuisine, no restaurant, $50 max2:28 GrokBot signs in to Uber Eats3:03 Checkout: $44.773:18 Order placed + a Friday breakfast surprise3:33 Waiting… and my Halloween zombie zone3:56 The Honda Accord arrives4:09 What did GrokBot pick?4:55 Founders Debate: live event announcement5:24 Taste test6:26 Friday morning: GrokBot ordered again7:05 Unboxing the Friday breakfast7:38 Where's it from?

DJ Builds His Own Website with Claude Code
A San Francisco DJ needed a website before clubs would book him. We sat down for a 30-minute conversation and Claude did the rest. The site was live before lunch.DJ Fed told clubs he played lasers-and-techno sets, but without a website they wouldn’t book him. So we recorded a normal conversation about what he needed. Claude Design turned that conversation into a full design system. Claude Code built a Next.js site from it. The site was pushed to GitHub and deployed on Fed’s own Vercel account. Nobody typed a prompt by hand. The flyers came from the same design system for free.THE WORKFLOW, STEP BY STEPRecord the client conversation. Just talk about what they need, who books them and what they want people to feel.Turn the recording into a transcript.Give the transcript to Claude Design and let it build the design system: colors, type, imagery rules and components.Give the design system to Claude Code and let it scaffold the whole site.Open a pull request on GitHub.Deploy to Vercel on the client’s own account, so the client owns the site.
