They should face criminal charges for any deaths caused by any of their cars' modes apart from "Rigorously Obeys All Traffic Laws" mode.
Yes. Related thought: I think Musk and other high level people at Tesla should face criminal charges for any deaths caused by their cars’ “Mad Max” mode.
And should have wrongful death liability exposure imo

about six weeks ago, I started running a play-by-post real-time "logistics wargame" I made, called Cataphracts. It started with 5 players, now it has 23. I've tweeted about it a bit, but here's a short blogpost with more thoughts and observations ⬇️ (link below)

Are people in non US universities and schools seeing this as well? Is this something the world is dealing with or did something fundamental break in our country?
An issue we're seeing at all levels of university is that many students are simply refusing to do *anything*. They aren't reading the syllabus, aren't following assignment guidelines, aren't engaging with material, ignoring deadlines. And this might seem like old news, but it truly has ramped up.

Its because they think they 'won' the Houthi experiment. They think they, with Israel, defeated Iran now and forever. They think Hezbollah is a completely defeated force. They think the USAF and SOF defeated ISIS and no one else helped. They think the only thing that matters in war is the violence.

In honor of Larry Summers, I asked the female members of my college class (1987) to say if they had any experiences with sexual harassment by teachers/professors, back when this was tolerated as, I dunno, the cost of attending college, and OH MY GOD.

Let me also say as a practitioner (of engineering not architecture but still) - falling back on the code is the easiest way to defend your expertise since code knowledge alone differentiates practitioners from like 99.9% of the population. BUT…
I think it also speaks to what we talk about when we talk about public policy expertise. Some believe practitioners are the ultimate authority on a given topic. But interdisciplinary analysis often offers a more macro view that can allow policymakers to truly weigh trade-offs.

I have some fresh questions about how Wolff got almost 18 months of unrestricted access to both the Trump campaign and, later, the West Wing to write his book (that curiously doesn't mention this at all to my knowledge)

For political hacks like myself, 'put it in the curriculum' is the oldest and hattiest of old hat policy ideas.
Why do we think schools should solve all our problems? What if we thought differently about life skills and civic education?

There needs to be trials and there needs to be people sent to die in a prison cell. Consequences must fall on the people who issued the orders and those who carried them out. We must make the punishment of these people a national spectacle that will be remembered for generations.

Mamdani's hero is LaGuardia. He just mentioned him again. And I maintain he has more in common with New Dealers than socialists. But you can't responsibly write about him without writing about the Milwaukee "sewer socialists" of 1910-60. Nothing he says is new, only the applications.

The way you do this is to stop dwelling on the arguments and talk about the people who are making them. The argument is wrong and absurd, someone who raises or persistently is a traitor trying to undermine the constitutional order. The problem is media won’t take this second step.
I don’t know how you do it, but we have to be a filter of “come on, you don’t really believe that” on these arguments. Nobody believes that the 22nd amendment contained a hidden path to reward the diligent seeker with more than two terms. Shut up.

If I were running the DNC, there would be Democratic Party sponsored food relief banks across the country right now that specifically welcomed anyone regardless of party affiliation.
Along with the food, there could be voter registration and links to runforsomething.net

It really sucks to realize that Bernie Sanders would have made a terrible president, because despite having a lot of integrity himself, he is an abysmal judge of character. Just fuckup after fuckup with the candidates who only get traction from his endorsement. His appointees would have been awful.
