scottious··on Marc Andreessen is wrong about introspection
> Hype can drown out valid criticism

It's funny you mention that because I remember at the time of HyperLoop somebody said "what about just ... trains?" and we all scoffed at it as if trains were some outdated technology

Let's just say I'm on team trains now.

scottious··on Marc Andreessen is wrong about introspection
Definitely not. The companies that were prototyping it all went bankrupt. The "Vegas Loop" is just a tunnel with Tesla car traffic in it and I don't even think they're fully self driving! Very very underwhelming. Not even remotely close to the "NY to DC in 29 minutes" which he promised.

We would have been much better off with investment in tried-and-true boring old trains.

scottious··on Marc Andreessen is wrong about introspection
I remember when Elon came up with the hyper loop idea and everybody I worked with at the time thought it was revolutionary. These were very smart people who were fooled.

In hindsight, how could we all have fell for this? What a profoundly stupid idea, but I distinctly remember at the time it felt right.

I guess what I'm saying is that I think a lot of people just wised up and started seeing through his B.S.

scottious··on Landmark L.A. jury verdict finds Instagram, YouTube were designed to addict kids
Personal responsibility is important. But at the same time, we don't let people open up a heroin shop and then claim it's your personal responsibility to not buy it and use it. We don't put slot machines in schools but tell kids that they need self-control to not get addicted to gambling.

I don't know what the answer is, but it feels wrong to lean _entirely_ on personal responsibility. We live in a world in which we were simply not evolved to live in. People literally make a good living by engineering and exploiting our weaknesses for profit.

> raise everyone with the forethought to know what might be addictive, the self-awareness to realize when you are addicted to something, and the self-control (and support systems if and when necessary) to stop

If only it were that easy. If you've ever known somebody who struggles with a serious addiction you'll know that even when they know it's destroying their life they still can't stop.

scottious··on Asian governments roll out 4-day weeks, WFH to solve fuel crisis caused by war
but then again, vehicle miles travelled per-capita has been mostly increasing in the US since as far back as 1975. There could be a lot of confounding factors. Like astronomical housing prices in urban areas forcing people live very far away and incur more VMT at a faster rate than WFH decreases VMT. I'm no expert here, I'm just spitballing.
scottious··on Asian governments roll out 4-day weeks, WFH to solve fuel crisis caused by war
Agreed. I care enough about it to sell my car, stop buying stuff I don't need, give up most meat, and live in a small energy efficient house.

However I do know people who really do not care. They may say they care but their actions and voting record show that in fact they don't care (or don't want to make it a real priority). But those same people get very upset when they're stuck in traffic

scottious··on Asian governments roll out 4-day weeks, WFH to solve fuel crisis caused by war
and if you're talking to somebody who doesn't care about climate change just substitute "climate change" with "traffic"
scottious··on Asian governments roll out 4-day weeks, WFH to solve fuel crisis caused by war
It's too bad that countries only consider things like this to address a crisis in fuel costs. Why not enact measures like this to curb the pollution and CO2? I guess it says a lot about what humanity truly values.
scottious··on Cardiorespiratory fitness is associated with lower anger and anxiety
Once you get over the hump and develop a certain amount of cardiovascular fitness, it stops being unpleasant and stressful.

The real problem is that most people don't feel like this is true. It really takes a solid 6ish months of earnest effort (AT LEAST 3x per week, probably more) to develop cardiovascular fitness. For some people, it'll take even longer.

I run an average of 6 days per week for the past 10+ years. At this point running is just about the easiest thing I do, it doesn't take any mental fortitude at all to do it. It wasn't always that way though, I used to dread it.

scottious··on Mark Zuckerberg grilled on usage goals and underage users at California trial
okay it's not a slippery slope, but it's something similar (that's why I said "feels like"). He's trying to establish a continuum of things that have a variety of addictive properties in an attempt to discredit the whole idea of addiction ("Don't try to make your video game fun, or some people may become addicted")..

> apart from very narrow categories, most people would not consider mere exposure to information or non-physical social interactions to be things that can inflict harm

That's an extremely disingenuous interpretation of social media. Huge straw man. We're talking about infinite-scrolling A/B tested apps that are engineered to keep eyeballs on the screen at the first and foremost priority for the primary benefit of the company, not the user.

scottious··on Mark Zuckerberg grilled on usage goals and underage users at California trial
this feels like a false equivalence and slippery slope fallacy.

Clearly things like cigarettes and hard drugs are bad and need very heavy regulations if not outright banned. There are lots of gray areas, for sure, but that doesn't mean we shouldn't take things on a case-by-case basis and impose reasonable restrictions on things that produce measurable harm.

Whether or not social media does produce that measurable harm is not my area of expertise, but that doesn't mean we can't study it and figure it out.

scottious··on Unprecedented 'Jobless Boom' Tests Limits of US Economic Expansion
This feels like such a weird non-sequiter argument, but I can't exactly put my finger on it. This comment seems to be asserting (1) government jobs don't produce value and (2) GDP is the only thing that matters.

I'm ignoring the fact that I don't actually know how government sector jobs contribute to or affect GDP.

Seems like by this logic, why not just cut ALL government jobs? Obviously that's a terrible idea...

scottious··on The US is flirting with its first-ever population decline
> they are often purchased to carry around their kids' friends as well

but it requires an adult to drive that SUV. Car culture has made it so kids don't have autonomy to move themselves around anymore. When I was 8 I used to be able to walk/bike around the neighborhood to see my friends. Then we moved to car-dependent suburbia and things were so much worse. Having to depend on adults to go places added a lot of friction. The end result is that we'd usually just spend a lot of time inside the house.

Just look at the dystopia we live in right now: some parents literally drive a Chevy Tahoe or equivalent SUV to school to drop their kids off. How many school-aged children can you fit into the blindspot of a car like that? Are we at all surprised that parents don't want their kids walking to school alone?

I literally have to tell my son to hold his breath as we bike by long lines of SUVs idling right next to a school

> People do what works for them within their budget, which often is a larger vehicle when you have kids

It's funny that I don't drive and I transport my 3 kids around almost exclusively by bike. Yet people who live in my neighborhood with kids insist that they need an SUV for all trips. (yes, I can afford any car if I wanted one).

I even organize bike trips so other parents can bring their kids to events by bike so we don't need to get cars involved.

I think we've fooled ourselves into thinking we need cars far more than we actually do.

Yes, there are dystopian places that are completely car-dependent and don't even have sidewalks, but even in places that aren't like that people still insist that they need cars for everything.

scottious··on The US is flirting with its first-ever population decline
I am friends with a lot of other parents already. I do go out of my way to make friends. I already organize bike trips to the museum and stuff like that. I'm a very social person.

What I'm saying is that there are a lot of forces keeping people solitary and anti-social. This is just one of them. I know for a fact that some of these families waiting in their SUVs live a short walk from the school. Yet still they choose to isolate themselves. Sometimes the kids in these cars are literally yelling out the window to my son because they're friends. I don't want him going close to the cars because they've LITERALLY been pumping out pollution for 10-15 minutes (those early spots are very coveted). I have to tell my son to hold his breath when we bike on the empty sidewalk past these idling cars. It all just feels very anti-social and dystopian.

Sure, school drop off is just one small aspect of life. But because of drop-off culture, there are certain people who I may NEVER have a chance to interact with. Imagine if those parents instead walked with their kid. Maybe I would make a new friend. Maybe we'd have a nice conversation.

Last year there was another woman and her son waiting with me. They walked to school every day. We became friends just through school drop off in the morning. It brought some happiness into my life and made me feel a sense of community. She could have chosen to get in her car and wait in the long line of SUVs like everyone else, but luckily she didn't.

By essentially saying "stop caring about school drop off and look for other opportunities" it feels like you're missing my point: building community means showing up in lots of different ways, and consistently. The school drop-off example is just one example of many. A woman who lived on my street since the 80s said that back then nearly everybody walked to school. By switching to a car-based morning drop-off feels to me like we've lost something, even if it's just a small thing

scottious··on The US is flirting with its first-ever population decline
However, he specifically said "will want to have children and feel/know that their children's lives will be good ones."

But this doesn't necessarily mean being richer. For example, many people are afraid of what unchecked climate change is going to mean for kids born today. No amount of individual or country wealth is going to fix that issue.

I have kids myself, but man... I really really worry about this. I do personally know people cite climate change as one factor in having no kids (or fewer kids). Some people even think that having kids will make it worse. They're not wrong...

scottious··on The US is flirting with its first-ever population decline
Housing for the boomers used to cost 3x the median salary. Now it's more like 6x the median salary. These are nationwide numbers. Wage growth isn't keeping up to pace with housing prices

Sure people can just move to a remote dying town and get a house for super cheap, but turns out people want to live within a reasonable distance to jobs.

scottious··on The US is flirting with its first-ever population decline
Every morning I get to my son's school about 10 minutes before the doors open. We arrive by bike and we sit ALONE on the benches near the front door.

Meanwhile, the curb is full of extra large SUVs idling with kids just waiting inside the cars. The long line of SUVs extends all through the neighborhood. My son and I are alone because people just won't leave their cars until the doors open. A vast majority of the kids live within one mile of the school.

It's just one small anecdote, but I feel like it illustrates an attitude I've seen.

scottious··on Parking lots as economic drains
> Cars are filled with people and people work and spend money.

You're conflating people with cars. You want people and you're assuming that all those people must be attached to a car. There are other ways to get people to be populate an area which brings me to my second point...

> If you rip out the parking you won't get a vibrant walkable downtown

You will if you build a lot more housing in that area. If thousands more people are able to live right there then of course it'll become more vibrant. That parking garage could be home to hundreds of people. Instead it's temporary storage for cars. The problem is that suburbanites are going to fight tooth-and-nail to bring their cars. So what you get is cars.

If that's what you want, so be it. That doesn't sound like a vibrant place if everybody has to drive a car to get there, though. It's traffic by design.

scottious··on Parking lots as economic drains
Depends on the trip. I've timed many trips bike vs. car in my city. Bike is usually faster (or very similar time) because the average speed through a city is actually pretty slow. There's a lot of "hurry up and wait" with cars (rush to get to the next red light) and on my bike I'm frequently passing long lines of cars stopped at lights.

And parking is a time sink. There's a place in my city that has huge parking garages with lots of parking but you still have to drive through a few levels of the garage, park, and then walk back down a few flights of stairs, then walk to your destination. I just park my bike right outside of my destination with the wheel lock. Street parking is always awful in populated cities, and I never have to worry about it. I always park right at my destination, where ever it is.

In suburbia, cars are faster because the average distance per trip is a lot longer. But it's ironic that the reason why the average distance is longer is BECAUSE it was built for cars so everything gets spread out! Cars are a solution to a problem that they created.

scottious··on Parking lots as economic drains
I don't really buy this argument. I live a happily (nearly) car-free life with 3 kids. It's not hard, it really isn't. I bike them everywhere, we take transit. I even do our weekly grocery shopping by bike. I bike them to school year round (yes, even today when it was 10F this morning). I wouldn't consider myself "hardcore" at all. I'm just your average middle-aged dad.

I use our car approximately once per week. In 2024 I used my car a total of 32 times (I actually tallied it out for the whole year)

It's really just a matter of city design. Do you think there aren't families in Copenhagen who need to get to their job and shops? They manage with much lower car mileage than the average American. American suburbs are car-centric and those cars end up clogging up urban cores where people are trying to live their lives.

Many Americans/Canadians probably cannot even imagine what my life is like. They can't even picture what it means to pick up a week's worth of groceries for a family of 5 on a bike (with a kid!). It just doesn't even register that this is a possibility.

scottious··on Parking lots as economic drains
That sounds like a recipe for getting a ton of cars into your city. Think of parking garages as "traffic generators". If you cater to cars you shouldn't be surprised if what you get is more cars. It's literally sending the signal to people that it's fine (and encouraged) to drive cars everywhere. After all, your tax dollars are paying for all that infrastructure

Maybe some people are fully car-pilled, but many people want to live in an area that isn't so car-dependent, it tends to make everything more spread out, noisy, polluted, and congested. It also imposes very large personal costs.

scottious··on The wealth of the top 1% reaches a record $52T (2025)
correct me if I'm wrong but isn't it just 1% of Americans, not globally?
scottious··on Ask HN: How can we solve the loneliness epidemic?
Parents need reliable childcare. A teenager or aging parents can't fill this gap reliably. I need somebody to watch the kids most days from 8 until 4. A high schooler won't be able to do this. My in-laws who live 1.5 hours away and have mobility issues (plus their own lives) can't always do that.

I agree we need strong community in close proximity, but still people need to travel to destinations a few miles from their houses sometimes. Biking is a great (this is my primary form of transportation) but even I know biking and walking cannot fill every transportation need. We need the trifecta of biking/walking/transit to ween ourselves off of cars and develop denser communities with more people to interact with in our day-to-day lives.

scottious··on What our childhood shows taught us about cities (2019)
I guarantee you that you'd never let your kids ride a bike on the streets where I grew up. I have three kids and it would be downright irresponsible to let them ride on streets designed solely for fast moving car traffic with absolutely no space anything but cars. Virtually nobody cycled and nobody walked on these streets. Even adults were too afraid to do it. There was not a single sidewalk in my town. The culture around where I grew up was that if you wanted to take a walk you DROVE YOUR CAR to a park and then walked there. Nobody and I mean NOBODY just walked on the street. Even the track team didn't run on the streets because parents were concerned about safety

This isn't an issue of limiting myself. This is just an issue of safety.

scottious··on What our childhood shows taught us about cities (2019)
I had a bike, I love riding bikes. These days, I bike everywhere all the time (I don't drive) but I also live in a bike-able place now

The roads where I grew up had no shoulder and people frequently whipped around the windy roads at 35 mph. The only bikers I ever saw were fully lycra-clad race cyclist type of people. I never saw a mother biking with her kid, for example. I was afraid to be on a bike on the streets. At least with walking I could take a step or two off the road when a fast moving car was coming.

scottious··on What our childhood shows taught us about cities (2019)
Having grown up in deep suburbia where I couldn't do anything without an adult + a car, I always marveled at the freedom that kids seemed to have in some TV shows. Even shows that weren't overtly urban always had these underlying assumptions that kids were meeting up without adults around to make it happen.

That sort of thing was impossible for me. No sidewalks, no pedestrians, barely any bikers. It was just cars everywhere all the time. One time I decided to make the 6-mile trip to the mall on foot. It was a harrowing experience, but I was a rebellious teenager and I just wanted some independence, even if it meant spending half a day walking just to go to a mall.

scottious··on What happens when the public lose confidence in academic findings?
For those who don't know, this is called motivated reasoning or confirmation bias. Once you can give a name to it, it's easier to notice it all around you. I'd argue that it's one of the biases that plagues humanity more than any other, our brains seem to be hard-wired to engage in motivated reasoning
scottious··on What happens when the public lose confidence in academic findings?
but this is not entirely academia's fault. I'm reminded of the ongoing conversation about alcohol's impact on our health. Over the decades, if you've consumed mainstream media, you've been told everything from "2 glasses of wine per day is good for you" to "no amount of alcohol is good for you" and everything in between.

What's difficult is that it's hard to communicate the nuance of what a study actually studied. How many people were involved? What were the methods used? What was the effect size? What were the confounding factors that couldn't be controlled for? None of this can be effectively communicated in a world that reads headlines and probably not much beyond that.

And of course, the media does sensationalize because they're incentivized to. You'll click a headline that says "alcohol is good for you, says science" but probably won't click a headline that tries to communicate the nuance.

scottious··on Music theory for nerds (2016)
I don't really think so. The stuff that's covered in the first half of this article is certainly very math-y, but you can be a great musician and not know this stuff. I really think all you need to know is basic arithmetic and the absolute basics of modular arithmetic (akin to learning how 12 o'clock + 1 hour = 1 o'clock, not 13 o'clock).

Becoming a great musician is more about developing your ear, technique, repertoire, etc. It's more similar to learning a foreign language than learning math, in my opinion.
