I definitely know at least one woman IRL that would post like that.
Aight let’s do a quick lesson in Bayes Theorem, here in a shitpost community.
Imagine there is a disease that exists in 1% of the population. Medical science develops a test with 90% accuracy (both in false positives and false negatives) on whether a person has the disease. Your doctor orders the test, and it comes up positive and saying that you have the disease. What is the probability that you actually have it?
Well if you test an entire population of 1000, 10 of whom have the disease, it will correctly positively identify 9 out of 10 who have the disease, and incorrectly give false positive results to 99 out of the 990 who don’t have it. So among the 108 people who get positive results, you only about 8.3% chance of having the disease.
My Bayesian priors for an anonymous prolific poster of thirstposts in a shitposting community on a heavily tech-centric social media platform is that they’re about 90% likely to be 30+ year old men. Claiming to be an 18 year old woman might move the needle a little bit, but not as much as you might think.

Some startups are trying to synthesize edible fats from non-biological feedstocks, using just energy, water, carbon monoxide, and hydrogen, through the Fischer Tropsch process.
Personally I’m more interested in seeing whether that can expand into just manufacturing hydrocarbons with excess solar energy, rather than synthetic food, but it’s still cool to see that people can do it.

I can do that. I’ll keep track of everyone’s food, you know, in exchange for food.

I’ll defer to your personal experience, but when I walk into a place like that (usually as a guest of someone who is actually staying there) I’m always like “ok I don’t belong here.”
I make good money but also don’t think I’d physically be able to swing some of the spending required at places like that. Like, I just wouldn’t have the funds in my bank account.

Most of the stuff in this thread
We probably need to talk about what one’s definition of “rich” is. I suspect the commenters in this thread are all over the place.
When I was growing up, my idea of rich was private schools and McMansions and overseas vacations and new BMWs for 16th birthdays, basically the kind of lifestyle accessible to only the top 5%.
But now, 20+ years later, I’ve been around 0.1%ers, desensitized to upper middle class stuff that the things I used to believe were signifiers of wealth barely register for me anymore. I’ve also been around descendants of former 0.1%ers who carry some cultural baggage from their families despite having “only” ordinary upper middle class income.
I read this thread and wonder where each commenter sits in how they evaluate richness.
- Comment on How do wealthy people know if the people they meet are wealthy or not? 1 week ago:
Kinda depends on the price of the place, right? A $500/night hotel might have a few upper middle class folks on a splurge (a honeymoon, some kind of points-based play on their credit card, etc.). A $2000/night place filters out the merely rich and leaves only the ultra rich. And a $10,000/night place isn’t even accessible as a bucket list item for even the 1% but not 0.1% types.
- Comment on How do wealthy people know if the people they meet are wealthy or not? 1 week ago:
I assume in your city, $4/month/sq ft isn’t considered “crazy expensive,” though. In a place like San Francisco or New York, a $2000/month apartment that is 500 square feet wouldn’t register as anything notable.
If it’s not considered “crazy expensive,” people wouldn’t assume you’re crazy rich just by living there.
- Comment on How do wealthy people know if the people they meet are wealthy or not? 1 week ago:
I don’t think this answer truly internalizes how some of the ultra rich live. Yes, many are living a normal looking life, going to their jobs and doing a lot of the same activities that the upper middle class do. They generally eat at the same restaurants, have the same hobbies, and enjoy the same television shows that the rest of the middle class does. Often they go to the same live events (sports, concerts, plays, stand up comedy) that middle class people do, and often don’t bother with luxury boxes or things like that. They’re members at the same gyms, and might plot out the same run trails as normal people.
It’s just that they tend to fly private instead of commercial, stay at very nice luxury hotels unique to that particular location rather than the chains you’ve heard of. They have multiple homes. They’re members of clubs that require a lot more money to keep up in. They have lots of paid staff, both seen and unseen, smoothing over their day to day lives, washing dishes and laundry, maintaining houses and cars and landscaping, making reservations and doing paperwork on their behalf, etc.
The form of stealth wealth isn’t that they’re all among us doing normal things, with no obvious indicators of wealth. It’s that they often aren’t even around us to begin with. So the sheer amount of time that they’re around non-rich people, and actively interacting with non-rich people, may be a tiny portion of their time. Even if they do a lot of the same stuff we do, and go to a lot of the same places we do. They do it in ways that don’t necessarily interact with us directly.

There are all sorts of filters:
- Expensive clubs. Members only associations like country clubs can skew towards the ultra rich. Yacht clubs and polo clubs are kinda an extreme version of this, but there are all sorts of organizations where the membership can be assumed to be rich.
- Expensive hobbies. Wine tasting, skiing, golfing, boating, horse stuff, biking, and traveling/vacations can range from the slightly expensive to prices that only the ultra rich can afford.
- Related to both of the above, expensive places. If you’re skiing in an expensive resort town, and hanging out in the lobby of a $2000/night hotel, you’ll probably only see employees of these places or other very rich people. Some have even layers beyond that, like an exclusive members only club in an expensive area, or a separate lounge for only people lodging in the most expensive rooms in the hotel. Or if you’re at a private jet airport, and weather causes delays and cancellations, standing around in the terminal might allow you to mingle with other private jet people. Or if you live in a crazy expensive neighborhood or building, your neighbors are pretty much guaranteed to be rich.
- Third party verification. Networking, introduction by mutual friends/acquaintances, even social media or dating apps where you have to prove your status/wealth.
It’s not all or nothing, either. Some places have a disproportionately high number of rich people but aren’t necessarily exclusive to the rich (private schools, certain types of clubs, certain types of activities/hobbies, public parks/restaurants/libraries/museums in rich areas). So a lot of rich people do mingle with the middle class, but often will feel comfortable letting their guard down more or less in particular places or in particular groups.

There are about 2700 billionaires in the world. There are probably about 10,000 centimillionaires in the U.S. alone.
Especially if you include family members, it’s not just a few dozen.

- Comment on Dumb glasses 2 weeks ago:
It’s not about wavelength, but about intensity.
At night, in darker conditions, cameras dial up their light sensitivity so that they can see faint light (the human eye does the same thing through the iris). So in that mode, they’re sensitive to the brightness that can be produced by human-made light emitters.
But during the day, they’re already set for sunlight levels of brightness so that blinding them in that setting will require more light than is feasible to produce using normal light emitting technology. Infrared or visible light.
Think about trying to blind someone with your car headlights in the middle of a bright sunny day. It just doesn’t work.
- Comment on A sudden epiphany. 2 weeks ago:
My version of this was still being among the smartest people at my good engineering school but realizing I didn’t have the discipline to thrive without externally imposed structure. I coasted on skipping classes and catching up just fine my first semester, but that didn’t last all that long (a year before I was no longer near the top of any given class, 2 years to where I was struggling to understand because my grasp of the prereqs wasn’t as solid).
So it took a few years to learn how the world doesn’t inherently reward intelligence for the sake of intelligence, but that intelligence is still a good tool towards accomplishing other things the world does value.
I’m still sometimes the smartest person in the room, but I’ve learned to stop assigning any value to that fact.
I’m pretty happy these days, and I directly credit my intelligence and introspection for that. Even though the “smart but lazy” label gave me some trouble early on, and I had a little quarter life crisis when I realized that being smart wasn’t enough, eventually being thoughtful gave me the flexibility to recover from some setbacks early in my career, has helped me with my social life, helps me manage the day to day life outside of work (finances, chores, hobbies, interests, family life, etc.), and otherwise has helped me set up the things that are important to me and find contentment in a chaotic world. It’s certainly a form of intelligence, just productively channeled at some point to make things better for myself.

- Comment on xkcd #3214: Electric Vehicles 4 weeks ago:
I only really know the U.S. market, but our top two selling new vehicles (Ford F-150 and Chevy Silverado) have a full EV options that are similarly priced as their gasoline counterparts. They start at $10k more than the entry level gasoline trim levels, but also have options/features included that are comparable to similarly priced gasoline trim levels. And these trucks are a bit unusual in that options and features can literally more than double the price while still carrying the same model name (cheapest F-150 is $40,000 and the most expensive is about $90,000 with full options).
Our third most popular vehicle is the Toyota RAV4, which is available as a plug in hybrid, but the plug in model doesn’t sell that well. But Toyota has been slow at actually wanting to build and sell EVs. The fourth most popular, the Honda CR-V, is primarily a traditional hybrid.
Skimming past some more pickup trucks, the seventh most popular selling car is the Tesla Y, and the most popular pure EV that isn’t available as any gasoline powered variant.
Looking at the actual EV platforms available in the US, most of the big plays from non-Tesla companies have happened in the last 5 years.
Volkswagen was a bit earlier than most, with a few specialized models launching in 2019-2021, but they didn’t really move that many units.
The Korean manufacturers Kia and Hyundai and their shared EV platform had a bit more success with sales volume, and started with 2021 models, so that their used EVs are becoming available on the used market.
GM’s big EV platform, the BEV3 (which also powers Honda’s EVs) launched with the 2023 model year, and most models started with the 2024 model year.
Ford has their Mustang Mach-E (beginning in 2021) and F-150 Lightning (beginning in 2022), but both of those are one-off platforms while they work to develop a modular platform for building multiple models with shared electric parts.
Skimming through the offerings by other traditional automakers, there’s BMW’s i series, which led to electric options for several of their models beginning in 2022, and Stellantis with a bunch of European models and a handful of American models hitting the market beginning in 2024 or so.
Pure electric manufacturers like Rivian, Lucid, Polestar have also released some models in the U.S., mostly released in the last 5 years as well.
So it really seems like the higher volume sales of new non-Tesla EVs picked up in the last 2-3 years, and there will be plenty of used options in the next 5 years. To me, it looks like an inflection point that can sustain EV as the default pretty soon.
- Comment on xkcd #3214: Electric Vehicles 4 weeks ago:
The economics are basically always shifting. Real world depreciation and maintenance don’t always follow the model projections, and neither do actual fuel/energy price projections. Electricity service has skyrocketed in a lot of places in recent years, while gasoline prices have remained pretty low, which obviously affects the accuracy of the calculations and modeling that were done 5 years ago. Not to mention, both gasoline and electric energy pricing vary heavily between place.
And, of course, the ever changing regulatory landscape might affect pricing and resale value, as well.
Plus the thing with cars is that most people aren’t buying the absolute bare minimum they can afford. People are willing to spend more on things: passenger and cargo space, performance, aesthetics, features/comfort, exterior dimensions that fit their own needs (for example, people who live in a city and want a car that can fit in tiny spaces), etc. For someone who is looking at total cost of ownership of something like mid tier or even luxury model, they should be comparing specific models they’d consider.
Ultimately, people need to do the calculation for their own specific situations. Someone in the market for a minivan in Detroit is gonna have different considerations than the person looking for a pickup truck in Dallas or a luxury sedan in Los Angeles or an economy car in Honolulu.
And as things shift, we’ll likely see more people make the decisions that are right for themselves in that particular moment. Including people who want to pay more for something not directly financially beneficial to themselves, whether it’s the driver who wants a manual transmission and the sounds of a revving internal combustion engine, or the person who would rather spend a little bit of extra money to do something more for climate change. Or the person who wants to boycott Elon Musk and will spend a bit more getting another non-Tesla EV.
At this point, my next car is almost certainly an EV, but I’m not going to prematurely sell my current car to make it happen.
- Comment on xkcd #3214: Electric Vehicles 4 weeks ago:
Depreciation is a massive slice of the pie in all cars, but EVs are hit even harder.
I think that’s a quirk of Tesla trying to preserve market share by aggressively cutting prices of their new models over the past 5 years, which naturally puts pressure on all used models on the road. I don’t think that can last.
If EV manufacturers are racing to compete on price, then the new EVs will get cheaper faster to where EVs are cheaper than ICE vehicles new. And if the EV manufacturers stop cutting prices, then that will alleviate that depreciation pressure.
- Comment on xkcd #3214: Electric Vehicles 4 weeks ago:
Maybe replace dead batteries with used but still somewhat working batteries?
Why not replace them with new batteries?
Also, you’re not engaging with the fact that the typical ICE car lasts an average of 12 years. If there’s a batch of survivors that lasts much longer than average and are accessible to the people of your country, what makes you think the same won’t be true of EVs when they get old enough?
- Comment on xkcd #3214: Electric Vehicles 4 weeks ago:
So if you’re in a country where it’s economically feasible to continue maintaining cars beyond 15 years, why wouldn’t you think that the much cheaper electric cars wouldn’t dominate the market even more?
Compared to the U.S.'s low adoption rates, EVs sell at higher rates in certain rich countries like Norway and Denmark, middle income countries like China and Turkiye, and poor countries like Estonia and Nepal. The cheapest EVs, globally, are cheaper than the cheapest ICE vehicles.
And that’s a problem for ppl who buy 20 year old cars.
The cost of maintaining a car to last 20 years can be applied to EVs and ICE cars alike. I suspect that EVs will be easier to maintain to those ages. In the U.S., that doesn’t really happen in large part because our labor and parts network is expensive enough that buying new is comparably cheaper than repairing, past the 15 year mark, for most vehicles. EVs don’t actually change the equation any.
- Comment on xkcd #3214: Electric Vehicles 4 weeks ago:
Batteries only last 5 to 10 years max,
Real world studies are showing they last about an average of 12-15 years on average, and every manufacturer has a warranty for at least 8 years, with many up to 10.
A gasoline car can be fueled in 30 seconds
The typical passenger gas station pump flows at 7.9 gallons per minute. For most passenger cars and trucks, with tanks between 15 and 35 gallons, that’s about 2-5 minutes of pumping.
A typical level 3 charger will take a battery from 10% to 80% in about 25 minutes. And chargers can be in places where gasoline pumps can’t be, like ordinary parking lots and garages. So the dual purpose parking where you can charge the car while you shop at the grocery store or work out at the gym or sleep overnight at home is just a completely different paradigm from what we’re used to.
The average car lasts about 12 years, by the way. EVs last basically as long as ICE vehicles. Which also makes sense, because it doesn’t have to mix the fluids that lubricate and cool with combustion residue and foul up the engine that way.
So your data is out of date, and those fears that were commonly cited in 2015 have pretty much proven to be false for the technology that was around in 2015. Now, in 2026, there’s been even more advances in managing battery/charging health and chemistry, with more of an infrastructure for maintenance, repair, and charging.
