@Jason I paid $1000, my two kids (under 5) were free and we skied 60 days mostly no lines, 3 different resorts. Killer deal

@FuturamaKing @californiapost Yes, why wouldn’t you just defect from the grid? Panels, batteries and natural gas generator. It’s almost worth it at current rates without the big connection fee

@JessePeltan Pretty wild call from 2016 when it was 0. Estimate is 240 twh of batteries needed for full transition. We currently produce ~1% of amount per year. Current estimates get us to 5% of that target annually in next 5-10 years, which means we’re < 30 years

I have a guest essay in @nytimes today about autonomous vehicle safety. I wrote it because I’m tired of seeing children die. Done right, we can eliminate car crashes as a leading cause of death in the United States @Waymo recently released data covering nearly 100 million driverless miles. I spent weeks analyzing it because the results seemed too good to be true. 91% fewer serious-injury crashes. 92% less pedestrians hit. 96% fewer injury crashes at intersections. The list goes on. 39,000 Americans died in crashes last year. More than homicide, plane crashes, and natural disasters combined. The #2 killer of children and young adults. The #1 cause of spinal cord injury. We’ve accepted this as the price of mobility. We don’t have to. In medicine, when a treatment shows this level of benefit, we stop the trial early. Continuing to give patients the placebo becomes unethical. When an intervention works this clearly, you change what you do. In driving, we’re all the control group. Cities like DC and Boston are blocking deployment. And cities are not the only forces mobilizing to slow this progress. It’s time we stop treating this like a tech moonshot and start treating it like a public health intervention that will save lives. Link to article below. 👀 this video of Waymo cars evading crashes with people and vehicles. I especially note the ones that require it having a 360° view. My sincere thanks to Alex Ellerbeck and @acsifferlin for their wisdom and sure hand in editing this piece.

@acekingspades @adamcarolla “Millionaires didn’t need PPP loans”. PPP was designed to save jobs, not owners. Eligibility was based on employees, not net worth. Dumb argument

@adamcarolla nice strawman. "I pay a lot in taxes so ethics don’t apply to me”. Congrats on paying what you legally owe. Still doesn’t explain why millionaires needed PPP loans.

No one asked her to give up her “career.” What career are we even talking about? When I met her, she was an assistant. If she were truly ambitious, she’d be doing something now but she’s not. During our marriage, she had every resource imaginable. A full-time nanny, housekeepers, her own assistant, and meals delivered daily. She had more than enough support to pursue any career she wanted. Unfortunately, the legal system in California continues to punish the person who actually works and earns.
Stride@a_strider_again

@Seven7Alexandra @skylarromines @adamcarolla She absolutely did give up her own career, and focus on managing their family, which Adam admitted gave him the stability to grow his career over the two decades they were together. You are wrong. (Being a high net worth family with hired help doesn’t meaningfully change that)

@merket @kevinnbass @bgurley The non-group got the same score as the right and left groups. Group think used to get you a higher score. Eg should i eat this berry?

Nope, you're missing the point. The study showed bias hits both sides the same way, but lefties use deep thinking to beat it better overall. That means groupthink's upgraded in online bubbles, pushing right-wing gut feelings over facts. Conformity's bigger than ever in echo chambers. "In other words, analytical thinking did mitigate ideological belief bias among both leftists and rightists—it improved accuracy specifically on valid syllogisms with unbelievable conclusions and invalid syllogisms with believable conclusions—but among leftists, it improved accuracy also for syllogisms in which validity and believability were matched."

@kevinnbass @bgurley His point is still valid. Whether it’s sharper reasoning for same side syllogisms or adaptive misinformation, one still performs remarkably worse on opposite side questions. I’d argue it shows group think is less important than it’s ever been

@bgurley That's not what this graph says at all. The total number of syllogisms gotten correct is roughly equivalent no matter where on the political spectrum you are. They're actually marginally lowest on the far left but the far right performs equally to moderates and the moderate left.

Today, my @tesla Model 3 saved my fiancée, dog, and my life. While using @Tesla_AI in Full Self-Driving mode on a morning drive to pick up brunch, we approached a green arrow to turn left. My car hesitated. I was confused and felt like it was going against my will. That's when, all of a sudden... Wham BAAM! A wall burst past us and T-boned the car next to us going straight. I immediately went to park and check on the driver. He was okay—a young 20-year-old by himself, physically fine. I gave him my number and sent him the footage later. Crazy the impact having an assistant watching 360 degrees around you can make on the people you love and your own life. @WhamBaamX

I will say, going from 1 kid to 2 is really fucking me up. We're in the thick of it now. It's doubly hard if you're ambitious because the time just disappears and you don't know where it went and you haven't accomplished much of anything.

@shellenberger What we need is the actuary analysis by the insurance companies. The sports handicappers know exactly how a player injury or new coach change the odds. What features are in their models and how do they change the likelihoods

Had a massive water reservoir been online, it wouldn't have made much difference to LA firefighters, say the media. In fact, it would have made a massive difference. And now a whistleblower has come forward to say the reservoir should never have been drained in the first place.

@evansammccann $500 for a season pass that gets me into resorts everywhere. 16 days this season with my 4 year old and never waited in a line more than a few minutes. It’s never been cheaper if you go non peak

Skiing is going to change. Day passes are insane (Whistler is $300+ a day) and the crowds are getting bigger every year. Food prices have increased a lot as well. I think we see people ski less often and do bigger trips. Go to more remote ski hills with less crowds, do cat and heli skiing, more back country skiing. Already seeing this trend shift.

Uber vs. Lyft is under-appreciated as a case study on the importance of intensity & ambition — as close to a pure A/B test as it gets Lyft had a year-long head start, paid its people better, offered more work/life balance, stayed in the US, focused on ride sharing Meanwhile, people at Uber literally had to ask for permission *not* to work on weekends for the first few years. I know someone in support ("comm ops") who "took" 3 weekends on her first year The company was run by an army of intense and, frankly, sometimes downright crazy mfs who would stop at nothing in order to win It expanded aggressively across both geos (opened in Paris as its first international city, after just 3 cities in the US, 18 mos after launch in SF), and verticals (Eats, Freight, Bikes) It made a lot of mistakes, no doubt, and its style made it an easy target for activists And still — Uber's market cap is now $140B, and Lyft is less than $7B If you ever wonder whether you should go harder

The Tesla Model Y is already the best-selling vehicle in the world, and is about to becoming the best-selling vehicle overall in the U.S. for the first time. An EV has never held the #1 spot. Not enough people are talking about this. This is incredible. This speaks to how incredible of a product the Model Y is: • #1 best-selling car overall in the world • #1 most American-made car • #1 best-selling car by revenue in the world (~$50B in 2023) • About to become the #1 best-selling vehicle in the U.S. • Lifetime emissions are lower than those of a comparable ICE vehicle after just 3 years of ownership • One of the safest cars ever engineered. Top Safety Pick+ by IIHS & received the highest overall score among any vehicle tested under Euro NCAP • Total cost per mile of $0.70, on par with Honda CR-V & Toyota RAV4 (5 years, 60k miles) • Gets better over time with over-the-air software updates

@BradMunchen It's like playing poker against very bad players. In the short term anything can happen. But if you don't panic and don't make risk mgmt mistakes, and just hold the short for the long term, you probably end up winning.

Shorting $TSLA is a bitch. Stock is up to nearly $225 in the premarket, or +6.8% since Tuesday vs $QQQ's -0.3%. Absolutely *zero* news out there driving $TSLA up this week. If nothing, horrible August sales should be tanking the stock.
Motorhead@BradMunchen

$TSLA is +3.1% while the $NDX is -0.2%. (Yesterday was $TSLA -1.6% vs $NDX -3.2%). Second day in a row that $TSLA massively outperforms the "tech" market. This could be manipulation. Watch the $TSLA options market. $TSLA

@dvassallo I almost always decline every procedure recommended by the dentist and never had a problem. Had a 43 yo friend recently say he always rebuffed the wisdom teeth removal and never had a problem. Made me facepalm. Don’t floss either

Took my 7yr old to his annual pediatric dentist appt last month (near Seattle) and the dentist found 4 cavities in his baby teeth, all needing filling and one needed a cap. The dentist said this had to be done with general anesthesia. Cost $2,750. We found it bizarre to have to put a 7yr old under general anesthesia, outside of a hospital, in a small clinic above a Starbucks, with full intubation and put on a ventilator, just to fill 4 cavities in baby teeth that would fall off on their own anyway. The dentist insisted the intervention was necessary because these teeth won't fall off in 5 years, and one of the cavities was almost guaranteed to become problematic. And that general anesthesia was required because of the length of the intervention. We had a bad feeling about all of this, and declined the procedure after considering the risks of general anesthesia outside of a hospital. The dentist gave my wife a lecture about how this is totally safe and they do it all the time, and that we should take some time to think about it, but we should come again after the summer to talk with them again and reconsider our decision. The dentist insisted this was the only way to proceed and that it would be very imprudent to postpone it. The entire rant made the whole thing feel even more shady to me. It felt like a Hertz rep trying to sell me car insurance at the airport. We're now in Malta, and took the kid to a local dentist for a second opinion. We thought we'd ask the dentist if we could do the fillings one by one, over multiple sessions, in order to avoid any sedation. And guess what? This dentist took a look at the kid's teeth, and couldn't find anything! Zero cavities. Perfectly healthy teeth. Not even a cleaning was required. We paid €15 and were sent home. Now, the Maltese dentist didn't do an x-ray. They said it would be an over-intervention to order an x-ray with no visible signs of decay. The Seattle dentist does an x-ray every year, and found the cavities from the latest x-ray. They never sent us the x-rays though. Is there a chance the Seattle dentist was right, or is this a classic case of violating the Hippocratic Oath for personal gain? The insistence on general anesthesia just didn't sit well with me, and smelled of malpractice in an attempt to do this procedure quickly and more conveniently (plus charge a lot more). What's your interpretation?
