> The cost of lab-grown meat will likely be several times that of regular meat, according to Wired. Producing meat in the lab “will never be done with anything remotely like the economics you need for food,” Pat Brown, founder of the plant-based meat company Impossible Foods, told the Post last year.

Obviously he isn't an objective observer but I wonder what the argument is to back up the claim that it "will never be done with anything remotely like the economics you need for food".

The delays, the cost overruns and the general bureaucracy surrounding the whole project are likely the reasons why it _didn't_ fail miserably. It's definitely not a situation where you want to move fast and break things.

I'm not sure if I'm optimistic about autonomous vehicles or just very pessimistic about human drivers. I have no confidence that the next driver making a left turn while I'm crossing the road won't kill me. I'm much more comfortable with a computer that is programmed to avoid killing me, even if the software may have the occasional bug, than with a human who may or may not prioritize my life over whatever else it is they have going on that day.

This might just be an assumption. We'd need to compare with childless couples. As a datapoint of one, I'm getting close to 40, just over 10 years of marriage without children, and this article describes my experience eerily well and has given me real pause.

I've been playing semantle.novalis.org daily. It's hard enough that I don't want to start again when I'm done and I like that everyone is playing the same game with me. The problem with this is that it's too easy to allow infinite guesses but if you don't get it in 5 you want to start again right away.

It’s surprising to me how many of my disparate interests, unrelated to my work in software, are represented here in HN.

This is the key. We like to blame people for being inactive and overweight, but we've designed our transportation and food systems so that only the most motivated can be anything else.

If a web framework in the Pyramids was discovered, it would defy our understanding of the history of technology and "simply shouldn't exist". It's a dramatic way of putting it, but it's really just saying that our understanding was wrong. It shouldn't exist given our model of the world, so our model is wrong.

> I don't understand why consensus jumped to the conclusion that there must be a new form of undetectable matter instead trying to figure out what we don't know about gravity.

Is it implied in "I don't understand" that "it's not understandable?" There is quite a bit of evidence that point towards dark matter and away from problems in our theories of gravity. We have direct evidence for forms of matter that do not interact with particular fields, it would be unsurprising to find other forms that are extremely difficult or impossible to detect.

Reluctance to ask stupid questions comes from a fear of rejection. I studied physics in undergrad and I found it pretty difficult, but wanted to be a part of the group of smart physics kids. It left me with a pretty strong fear of looking stupid and a reluctance to speak up in class when I didn’t understand.

Not minding if you might sound stupid comes from a place of security in your life. If you already have a solid in-group, then the fear of being rejected by some other group starts to go away and you feel more comfortable risking looking dumb in front of people.

I think it comes from a deep instinct to find allies and show that you’ll be a valuable member of a group, or at least not a liability.

Generally in the 100Hz or 200Hz range for the time being. What do you mean by break apart?

Can you talk more about why you should use Postgres unless you have a compelling reason not to? I'm currently investigating options for storing high-frequency data. Postgres is looking like a good option.

You may be missing my point. If no one believes in the country’s existence, including the people who live in the land that the country is purported to encompass, then it doesn’t exist. Nations aren’t tangible physical objects. They exist in the collective human imagination. Yes. Your passport is just a notebook if no one believes in the country it is supposed to be for.

It exists only when people believe it exists. If no one believed in your citizenship, your passport would just be a little notebook with no value. When going from a world without citizenship to a world with it, nothing needs to change outside of the human brain. In that sense, it’s a fiction.

> It's either a fiction or it's real.

This I disagree with. Nations are real in the sense that they have a material impact on the world, but are fictions in the sense that they only exist when people believe in their existence. It's like money. Obviously money is real - I have some in my wallet right now - but if no one believed in the currency then it wouldn't exist. It would just be pieces of paper.

> Nations as constructed obviously provide value to the people residing there

I would quibble with the assertion that this is the _reason_ nations are constructed, but I do agree that they provide value.

Some people's lives are just more complicated. I'm a dual citizen myself, with two citizenships from birth. I was born in Canada from two American parents. I've had two passports all my life. I happen to live in the US but I've never really chosen one country over the other. I derive identify from being a citizen of North America. There are plenty of people with slightly more complicated than average stories, they should be able to exist.

Based on this post, apparently citizenship is also voluntary. You might say that giving up citizenship is difficult and expensive, but you should talk to someone who has gone through a divorce.

I would also counter that citizenship also almost always necessitates an emotional element. Citizenship is a primary part of many people's identity, and identity is the most emotionally charged thing of all.

Citizenship is a meaningful thing to most people. Of course it's a legal fiction, but so is marriage. Personally I've never given up a citizenship, but I imagine that it'd be an emotional experience.

I was excited about Yang’s candidacy in the NYC mayoral election, but it didn’t take very long to see that he was out of his depth. In the end, he didn’t even rank in my top 5 (NYC has ranked choice now). Why does he keep running for top positions? He clearly doesn’t have a record of success as an executive, either in private or public sectors. He seems like a nice guy. If he wants to get into politics, why not start as a city councilor or something?

I don’t think it’s accurate to say that DDD advocates ignoring how things relate. It’s more like finding the higher level concepts that do relate to each other. You don’t need to know about internal combustion to write traffic rules. In fact, it’s better if you don’t know about that because your rules shouldn’t need to change when the mechanism that moves the car changes.

I wouldn't expect the pilots to spend an hour debating before every takeoff, but rather to have had that debate ahead of time and have a solid set of patterns that they follow so they don't have to reinvent the wheel each time.

The fact that attention to code doesn't prevent all problems doesn't mean that it doesn't prevent some problems.

People often point out how the US is an outlier in religiosity as a western, wealthy nation, but I've always wondered how it would break down if you corrected for its diversity. For example, there are a lot of first and second generation Italian immigrants in the US, how does that population compare to Italy? There are a lot of Mexican immigrants, how does that population compare to Mexico? The older groups from protestant countries, how do they compare to Germany or the UK, and so on.

> I've seen a few videos from various Universities

I've also seen a few videos from various Universities. _Remarkably few_, given how much attention this topic gets.

This seems to be the case. Watching the Spanish dubbed version of Community on Hulu, the dubs have the study group taking an English class, while the subs have them in a Spanish class as in the original.

Side note: in the dubbed version, it's hilarious when they switch to speaking bad English where they would have switched to bad Spanish in the original.

Even if one of the most famous photographs ever taken wasn't called "tank man", it'd still be pretty weird for there to zero results. Try misspelling "man" or "tank", you'll get many results. "tanke man" says "including results for 'tank man'".
