What they believe
-
A privately owned self-driving car is a hard sell, because the owner inherits the cleaning, calibration and liability a fleet operator normally carries.
I wish Tensor the best, but I think this is going to be a hard sell.

Tesla's first robotaxi service went about as well as it could have, and the failure clips that circulated were not representative of it.
These videos exceeded my expectations. Tesla’s robotaxi rollout wasn’t perfect, but it went as well as anyone could have expected.

What I learned watching 78 videos from Tesla's Austin robotaxis Said 8 Jul 2025
A good robotaxi demonstration in one city does not mean the company is ready to scale the service.
But I don’t think Tesla’s accomplishments over the last two weeks—impressive as they are—mean that Tesla is ready to quickly scale up its service.

A large majority of the serious crashes a robotaxi is involved in are caused by the other road user, not by the robotaxi.
Even if we assume all three of these crashes were Waymo’s fault, that would still mean that a large majority of the 38 serious crashes were not Waymo’s fault.
After 50 million miles, Waymos crash a lot less than human drivers Said 26 Mar 2025
A robotaxi that still needs remote human help loses the cost advantage that motivated it, which pushes out when it can scale.
If Waymo vehicles were constantly asking for remote guidance, Waymo might need to hire so many remote operators that it negates the cost savings that come from not needing a driver.
On self driving, Waymo is playing chess while Tesla plays checkers Said 21 May 2024
Tesla has not found a better route to driverless cars; it is simply years behind, working on problems the leader solved long ago.
So Tesla hasn’t found a different, better way to bring driverless technology to market. Waymo is just so far ahead that it’s dealing with challenges Tesla hasn’t started thinking about.
On self driving, Waymo is playing chess while Tesla plays checkers Said 21 May 2024
A huge fleet collecting driving data is not a silver bullet for self-driving, because the data arrives unlabelled.
But while access to more data is certainly helpful, it’s not a magic bullet. One issue is that the data Tesla collects is unlabeled.

The evidence that driverless cars are already safer than human drivers is piling up, especially for Waymo.
But the evidence for better-than-human performance is starting to pile up, especially for Waymo.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

- Elections are (in part) a performance to convince the public that the result is legitimate. Blue state policies like automatically sending absentee ballots to every registered voter signal indifference to fraud. This seems bad regardless of actual fraud rates. 28 Oct 2026
- Ilhan Omar says she was 8 when the Somalia Civil War started — generally dated to January 1991. This is consistent with Omar's October 1982 birth date. But right wingers are pretending she wrote that she was eight in 1989 because that would support immigration fraud accusations. 26 Oct 2026

- A lot of hostility toward creative use of AI is based on the premise that we'll eventually reach the point where the AI is doing the thing rather than you doing the thing with the AI as a tool. I think this is wrong — if it's your idea, it's your creation. 19 Oct 2026

- To be specific, the pattern of the last 4 years has been lab insiders correctly predicting rapid capabilities growth while overestimating the likely real-world consequences. I expect a continuation of both trends in 2027. 16 Oct 2026
- I used to employ a nanny and now employ @chi_t_williams. This has broken DC's tax system (household employers are considered separate from regular businesses) and I'm therefore unable to register to pay unemployment taxes. I've been on the phone for days trying to fix it. 16 Oct 2026
- Disappointingly ignorant article from the Atlantic. There are rare times like 2009 when a lack of demand hurts the economy. But in general too much spending can cause as many problems (i.e. inflation) as too little. There's no general problem from people saving too much. 16 Oct 2026

- "People inside the AI labs claim to have evidence that makes them more worried. And they are not allowed to talk about it." I have trouble taking this too seriously because it's been true for almost the entire 3.5 years I've been covering AI full time. 16 Oct 2026
