As a technical writer, I believe default AI responses are optimized for what people _think_ is good writing rather than what actually is good writing.

My guess is years of RLHF optimized for rater's first impressions of how well-written something was. It uses lists! It has headings! It uses fun phrases like 'smoking gun'! It's long and informative! These things are relatively fast and easy to identify and select as a preference.

But none of this really covers whether the response is _useful for the audience_. If you're not the audience, it can be hard to tell what is and isn't useful.

Dumb question: is there a limit to how much energy we can capture? I'm imagining a wind gust blowing east to west across a city filled wind turbines. By the time the gust reaches the west end of the city, has most of its energy been captured or otherwise dissipated?

Contrasting that with solar, where any surface area receiving direct sunlight doesn't prevent other adjacent areas from also capturing solar.

The other end feeds into itself too. Someone who posts something like that also is over-exposed to content enforcing that narrative. When you see your 50th video of the day of (e.g.) a man behaving in a way you don't like, you eventually conclude that men are all bad, and your reactions begin to become more and more pronounced. You're not reacting to that man, you're reacting to every man!

Nowadays there's the risk that someone will record you, put it on social media, it'll go big, and suddenly you have a large amount of people weighing in on your personal life without having any context. If that happens, it's likely to trickle back to you directly from other people seeing it or whatever.

The conclusion was made from a 30s clip, and no amount of evidence can overturn that. New theories will be created to support the original conclusion to avoid any amount of critical self-reflection.

I had my first kid a couple years ago and found myself spending a ton of time holding my kid while he slept, since it's the only way he'd reliably sleep. I spent a good amount of that time browsing various parenting and new baby subreddits.

One very common pattern I saw is that the conclusion is always that the dad is useless. Any provided facts are downplayed. Any omitted facts are imagined in the most negative light possible. And to be fair, there really are LOTS of cases where the dad is useless. The issue is more that posts needed to contain a mountain of evidence to return a neutral ground where the dad is no longer seen as a piece of garbage, rather than starting from neutral ground.

I feel for moms, who in addition to giving birth and having their lives upended to raise a baby, are now told that not only are most men garbage, but their man is garbage too. I feel for the dads, who even if they work hard are told how useless they are, and have to combat a stream of negativity fed to their spouse. It's a divisive wedge thrown into a new family, one that social media algorithms are only happy to encourage for engagement.

When I see instances like the one in this topic, I can see how the default narrative has been applied here. The radio announcers surely aren't aware of the storm they're creating, but it suddenly thrusts two average people into the social media spotlight, where people are happy to assume any missing details to fit their narrative. Everyone is going to apply the default story without taking any time to consider the possibility of other context.

EDIT TO ADD: I know there are manosphere spaces that are toxic too. As a man I've had no problem avoiding them, so this is one of my first extended exposures to this type of content, which is why it stuck with me. Probably also because I felt personally unwelcome as a dad.

I agree a lot with this. Some folks really do hoard pointless things, but for most people a lot of their stuff really consists of things you'd expect to be in a household, but rarely use. It doesn't usually make sense to get rid of these things pre-emptively because you're still likely to use them as long as you're in that living situation, even if it's infrequent.

Then when you pass away and other people have to go through it all, they don't need those items because their household already has those items. I don't need 3 more flashlights and a kitchen table because I already have my own!

I agree a lot with your point on Minecraft. The farther you explore and the more you see, the higher the bar feels for what's worth your interest.

When you first start playing the game, a medium sized mountain is exciting. Then the bar raises towards more interesting features (a deep canyon or a village), and then towards really interesting features of land. Finally, you look for obscure biomes (e.g. badlands or ice spikes). By the end, you can go thousands of blocks without seeing something that feels worth exploring.

Luckily Minecraft has other aspects beyond just the exploration.

There are different ways to take it.

There's the Kerbal Space Program approach, where space exploration is tough and you need to learn a LOT to succeed at it. The tradeoff of this is a high sense of accomplishment, where simply landing and returning from another body feels like you did something incredible.

There's also the Outer Wilds approach, where the story carries it. Moving around isn't hard at all, but you have specific goals to accomplish that move you towards a final ending. Diversity in how you accomplish those goals makes it feel fresh.

Mass Effect is similar, where you have some freedom to explore, but it's again in the pursuit of this broader story. So exploration feels like a rich side quest more than the main point of the task.

I agree with this. People buy a place to live usually because they like the qualities of that place. Changes to those qualities affect their day to day experience, whereas changes to their primary residence value usually only materialize when they need to access that value.

To me the issue is that densification (in the US; can't speak to other countries) usually comes with more downsides than upsides.

Mainly this is because of the US's focus on cars: the biggest downside is usually increased traffic. Unfortunately it feels towns in the US do the bare minimum to address it, like adding some traffic lights and maybe a lane or two.

Instead I wish the US had more good examples of densification for existing residents, where along with the increased housing larger steps were made to improve the community. E.g. significantly expanded mass transit, bicycling infrastructure, community third places, etc. And I get it, these things are really expensive and hard to do. But turning densification into something that more clearly benefits the day-to-day experience of existing residents would do a LOT to combat NIMBYism.

As a physics major I agree a lot with this.

Most of my courses were very "Point A" to "Point B". You're given a set of formulae, then a problem, then you use some combinations of those formulae to solve the problem. Most labs were the same way: you're given an exact script to follow without any explanation of the experiment design. It felt like both were optimized for easy instruction / grading and not for learning new skills or concepts.

Only two of the courses I took were substantially different. One was an upper division lab that actually was more open-ended, where we were given a goal and some equipment and had to figure out how to use the equipment to meet the goal. Another was a more conceptual course where we explored how to approach broad problems to come up with rough estimates for a wide variety of questions. Both were much more engaging, but I saw many students good at the typical course type struggle with how open ended these courses were.

Thinking more about this, I feel a good solution might be to let students decide whether they want to keep the first semester letter grades once they receive them, or simplify them down to a pass/no-pass.

That way there's still an incentive to do good work, and students who do well still get to receive the benefit of keeping the letter grade. Students who do poorly receive the letter grade as feedback, but have a one-off chance to reduce the impact and try again the next semester.

I'm not sure how to feel about this.

On the one hand, this is good for people who need time to adapt to college. It's a big change, especially for young people who are living apart from family for the first time. You have to adapt to living alone AND an entirely new social environment AND a much more independent/rigorous academic environment all at once.

On the other, it may just delay the same result. If someone knows their first semester doesn't really count, they may not put in the time to adapt, then crash out anyway in the second semester when it becomes real. I also feel our society tries a little too hard to insulate young people from failure, and I wonder whether that means people avoid learning important lessons earlier.

I guess the biggest advantage is it lets someone spread the growth out over a little more time rather than getting railroaded at once. This approach is probably most useful for someone who is genuinely trying and struggling, rather than for someone who is not really putting in any effort. It's probably better to help the former, so overall it's probably a reasonable approach.
