When there is a need (remote space colonies for example), they might need to develop a more robust process that would trade off size and speed of chips for ease of manufacturing.
OTOH, remote space colonies get zero-g manufacturing, along with free vaccum so hard that makes our best artificial vaccum systems seem like a Florida garden during a hurricane in comparison.
What they get to do may not help with DIY in a garage on Earth.
Zero-g adds nothing. You cannot even purify silicon in zero-g, you need some-g for impurities to go up and down.
The average distance between molecules of the atmosphere is 3.3nm, this is about 10 times of the typical atom diameter. You need 1/1000 of the standard atmosphere pressure to make this distance ten times bigger. Which will pretty much be the hard vacuum at the scale of the atom manipulation.
> You cannot even purify silicon in zero-g, you need some-g for impurities to go up and down.
Only if you're using the purification technique that was developed for use on Earth that takes advantage of Earth's gravity.
There's other ways to purify silicon. Off the top of my head and not because it's necessarily a good idea even in zero-g*, there's the Calutron: https://en.wikipedia.org/wiki/Calutron

That's famously how gases differ from liquids and solids, yes.
I'm more pointing towards it being easier to control the doping of the semiconductors when you don't need to worry about the presence of oxygen (or water vapour), and that this is a very very clean "clean room" that you get for free without having to filter out the dust** or pollen because there wasn't any in the first place.
* it might be cost effective or not, I'm making no claim either way because I don't care enough to try and engineer something like this and then compare it to the alternatives
** depending on where you go in space, of course; I'm just saying you can pick a place without any, you're not obliged to do this e.g. next to an asteroid.
Car traffic might be reduced per capita in higher density areas, but all of it is concentrated and is right near all the people. Multiply by the sirens of ambulance and police that are constantly going somewhere. Compare to a dead-end suburb street which only 5-10 cars have any reason for driving at all.
You've apparently never actually been in a suburb. They typically have random unkempt forests behind each row of houses, and not just a little bit. Like you need a serious walk between houses on different roads, and all of that is a long unbroken piece of nature.
The front of the house near the road has the lawn, but there's a LOT more to suburbs than that.
2 minute walk from where I lived in a suburb was a "forest" as I called it as a child, so large you could get lost. In the suburbs where my relatives live there's more forest with bears, and a there's a creek behind their house.
Yet from the front it's a road with lawns. There's a lot more to suburbs than that road.
Not to mention kids love playing in that road since there's barely any cars. All those car-free threads, about how cars ruin things? Suburban kids already have that: They have barely any cars to contend with.
Indeed, some suburbs have a lot of nature. I've encountered suburbs where individual houses are in the middle of the woods, off the main road, and yet not 10 miles away are developments where all the houses all look identical because they were built by the same developer and have a lawn in front, a backyard, and no wilderness whatsoever; right outside that development are busy streets on all sides.
I've lived in suburbs that are incorporated cities with population above a hundred thousand, and are eminently as pedestrian-friendly as some larger cities, but are tiny in comparison to the city that they're suburbs of (with more than a million people within that city's limits). And there are suburbs where you cannot get to the nearest grocery store without getting in a car and driving on the highway for 5 minutes.
You can't paint all suburbs as having lots of nature and being devoid of cars, just as you can't say all cities are identical.
Yeah, I grew up in a town like that in CT. It's nice, for sure. I would call it semirural rather than suburban, though.
The issue with lovely semirural living is that there literally isn't enough space on Earth for everyone to sustainably live like that. It's a privilage to live in house surrounded by woods with grocery store a 15 minutes drive away. Many people (not you, congrats) need to live very close to one another, and the best, happiest, most sustainable way for them to do that is in a dense city with good transit, good sidewalks, and limited auto traffic.
That is all not to mention the economics of suburban and semirural living. Those nice roads with little traffic? They are crushingly expensive. Towns would not be able to afford them if it were not for huge federal and state subsidies, which are largely funded by... wait for it... tax revenue from dense cities.
It's not semirural - there are no farms or fields anywhere, and there are plenty of houses. It's just they are spread far enough apart for people to have space.
> that there literally isn't enough space on Earth for everyone to sustainably live like that.
That's really not true. Half of the US lives in cities, half don't. You really think the US is so completely full there's no room for those city dwellers to have more space?
According to my quick math there enough room for 40 times the population of the US to each person (not each family - each person) to have a huge suburban lot.
> They are crushingly expensive.
No, they are not. That's an urban (ha!) myth. Roads are really not that expensive once you move out of dense cities. Rural roads cost around half or less of urban ones, and they last around 4 times as long since traffic is much lower (5-10 years vs 25-40 years). So a rural road costs like 1/10 an urban one.
And since according to http://demographia.com/db-intlsub.htm suburbs have around 1/3 the population density, suburban roads are actually 3 times cheaper per person!
Hardly "crushingly expensive".
> Towns would not be able to afford them if it were not for huge federal and state subsidies, which are largely funded by... wait for it... tax revenue from dense cities.
And cities would not exist if not for all the goods made in non-urban areas. Cities have tons of high-revenue, high-tax services, but they don't actually make anything. That's all done outside the city.
If everyone moved to the city everyone would die - there would be no food or anything else.
There's a balance in the world between cities and rural and suburban area, and you mess with that balance at your peril! You can end up with terrible imbalances and very expensive food and other goods.
And don't forget you need all those rural roads, or nobody could get any goods to cities. So be doubly cautious about suggesting fewer rural areas because of "road costs".
man I’m curious what state or country this suburb is in? The suburb I grew up in was nothing like that. If anything you’re describing something more on the rural side of things.
Due to my privacy I'd rather not say the city name, but I will say it was the second largest city in a strongly Democratic coastal state.
The largest city in that state was one of those large city hell-holes with too many people crowded in too small a space. But the second largest city was quite nice once you were not too near the downtown.
It’s interesting how much variation there are for suburbs. I’m mostly used to the types that exist in CA which are very different from what you describe and I am personally trying to avoid settling on. Also as someone who lives in a “large city hell-hole”, I personally greatly prefer it to the suburbs I grew up in. Fwiw a lot of the urbanism movement I’m familiar with prefer rural areas and cities over suburbs. You’re right that cities can’t exist without rural areas and the idea is to make more areas rural, not decrease it. The main issue that is brought up is suburban sprawl, which I think is different from what you’re describing. I think the main idea is to avoid cities like LA and prefer more density like Chicago or NYC.
My experience is that dead end suburb streets with no reason to drive on them are constantly used by hoons doing burnouts or modified motorbikes making loads of noise at 1AM
Those black rubber playgrounds (not sure if that's the same) smell like a chemical factory exhaust on a sunny day (you can also fry some industrial-solvent-laden eggs). Not sure about actual health effect, but experience is far from pleasant...
I share all the reservations about this flavor of "safety", but I think you misunderstand who gets protected from what here. It is not safety for the end user, it is safety for the corporation providing AI services from being sued.
Can't really blame them for that.
Also, you can do what you want on your computer and they can do what they want on their servers.
Humans _are_ inherently "made human" by a long path of evolution. We have a set of conflicting heuristics that serve as our initial values and which are more helpful than harmful on average. We then use those to build our moral patchwork.
Pretty cool that evolution has helped us work out consistent and rational solutions to the ethics of gun ownership, abortion, and nuclear proliferation.
No only the basics related to survival have evolved instincts. modern concepts like abortion did not have millions of years of natural selection to evolve instincts.
However it is universally reviled to kill babies or rape toddlers and slice their faces off for food. This is identical across all cultures. The basest morals are universal and so is disgust, the high level ideologies like abortion are just made up.
These high level ideologies are attempts to make sense of moral instincts that only existed to help us survive. For example abortion. It's the extension of your instincts to avoid killing. At what point does decapitating the head of a fetus to abort the birth become disgusting? The third trimester or before that? You're trying to rationalize your base moral instincts into a codification of law. It's almost pointless because these moral instincts weren't evolved to be logically cohesive anyway. They're just like feelings of hunger and pain.
Evolution never had to answer that question so it didn't give us any answers. But decapitating a 1 year old baby? Now that's universally reviled because it effected the survival of the human race. It's so reviled that I may even get voted down for using this as an example. It's the perfect example though, the revulsion is so much stronger than abortion that some people can sense that it's not a cultural thing but more of an inborn instinct.
The practical consequence of abortion and decapitating a 1 day year old baby are virtually identical though. But even someone who is against abortion will still sense a gigantic difference. That sense is an illusion, a biological instinct that bypasses your rational thought.
Yes, I feel, may not be correct, that plug-in hybrids are a little underrated. Most have very short ranges, I wish the range could be longer. Rav-4 has the best range that I know of, but they are hard to find and with the newer tax credits hard to justify, as they are not built in the US they don’t qualify for tax credits.
OTOH, I hate oil changes, so that is my personal reason to go full EV since technically they require less routine maintenance as they are simpler.
> I don't think that release was a surprise to the board
Unless this is exactly the kind of lack of "candor" and "break of communications with Sam" really meant, on the original accusations after the firing.
Either that or Adam wasn't paying attention (?), or told Sam not to, and Sam went ahead and still did it as a big fuck you to Adam.
Given how buggy GPTs are (you can't even set up actions with auth, "internal server error") that seems like a very hurried release. Maybe hurried enough so that the board didn't even see it coming.
Oh, I didn't know that! I can't get to the citation, but per Wikipedia [1] Hydrophilidae, the family in which this beetle is classified, do have that capability. Whether even with an air bubble they can hold out long enough is a separate question, as is whether their also-mentioned ability to extract usable oxygen from ambient water would be helpful in this environment - but being able to carry air under their elytra would certainly improve their odds.
