The Game Theory of How Algorithms Can Drive Up Prices (quantamagazine.org) 1

Computer scientists at the University of Pennsylvania have proved that pricing algorithms can drive up prices even when they lack the capacity to collude. Aaron Roth and four colleagues studied so-called no-swap-regret algorithms, which are designed to minimize losses and were previously thought to guarantee competitive pricing. The researchers found that when such an algorithm faces an opponent using a nonresponsive strategy -- one that randomly selects from predetermined price probabilities without reacting to competitor moves -- both players can end up in equilibrium at high prices.

Neither has an incentive to switch strategies because their profits are nearly equal and as high as possible under the circumstances. The nonresponsive strategy cannot express threats because it does not respond to opponent behavior, yet it effectively coaxes the learning algorithm into raising prices. Mallesh Pai, an economist at Rice University not involved in the research, said the finding matters because regulators have no clear grounds to intervene without evidence of threats or agreements. Roth conceded however that he lacks a solution to the regulatory challenge his team identified.

First, the possibility that a few human drivers are safer than robotaxis, isn't really relevant when it comes to the overall safety of the technology.

You seem to really not care if people are killed by robotaxis, you still think people will "actually like it"

Seriously my man - you might try an approach that doesn't make you sound pathological - because you definitely do.

Trivializing deaths while claiming superior safety isn't a good look

We will *actually like* the steep *reduction* in fatalities that occur as robotaxis become more common. Some studies already show robotaxis being safer than human drivers. Even if those are arguable now, as robotaxis get better, they will very much outperform humans on safety. There is nothing to dislike about that.

The problem is, people aren't rational and the news loves to sensationalize things that are new. Case in point right now is EV fires. Every EV fire is a newsworthy event, and I've often heard acquaintenances dismiss EVs as "fire traps", completely ignoring the fact that gas cars frequently catch fire.

Auto deaths happen in abundance every day, yet barely merit a news story. But the first time a Waymo kills someone you can bet it will be national front page news, and it's all anyone will talk about.

True enough. I remember when the first Tesla fire was news. People were claiming that all EV's are fiery death traps. I even had some in here claiming that ICE vehicles almost never catch fire - they do every day.

That said, the resources that Robotaxi companies have and the need for them to claim their vehicles are the very zenith of safety, I'm expecting then throwing those resources into claiming the dead people were wrong, or NDA compensation to the non-dead family members.

When a kid gets killed, that kids parents is unlikely to be solaced by the fact that other kids are safer.

Well one guy here says we'll actually like it that the kid was killed.

I agree with you. "Actually liking people getting killed was kind of a sociopathic thing for him to say.

This robotaxi thing reminds me of some years ago people were saying that the cloud was perfectly safe and secure. That one aged like milk. This one might too.

Who is liable when the Robotaxi acceptably and we like it when they kill people? I mean if we like people being killed, maybe there is no. liability, just a celebration.

Dude - yer a sociopath saying we'll actually like people being killed.

Yes, the exact hour at which the change is made is adjusted for timezone, and based off UTC (so including leap seconds).

For automated systems, they have to account for that difference when calculating DST times. It annoys users because they expect it to "just work", but unless the system knows which timezone it is in then it can't be fully automated.

It would be better to just not bother with it, and if particular groups want to have different summer and winter opening times they can do that themselves. It's not like every shop and business opens at the same time anyway.

Nvidia Becomes World's First $5 Trillion Company 13

Nvidia became the world's first $5 trillion company on Wednesday after its stock climbed 5% in early Wall Street trading to push its market capitalization to $5.13 trillion. The Silicon Valley chipmaker reached the milestone three months after hitting $4 trillion and three years after it was valued at roughly $400 billion before the debut of ChatGPT.

Nvidia chief executive Jensen Huang said Tuesday that Nvidia had secured half a trillion dollars in orders for its AI chips over the next five quarters. The stock had already gained 5% on Tuesday and added more than $200 billion to its market value. President Donald Trump said Wednesday he planned to discuss Nvidia's Blackwell chip with China's President Xi Jinping when the two leaders meet later this week. Nvidia's latest generation of graphics processing units is not currently available in China because of US export controls. The company's shares have risen more than 85% in the past six months.

Gates Retreats From 'Doomsday' Climate View, Prioritizes Aid To Poorest Countries 8

Bill Gates is retreating from his earlier warnings about climate change. The Microsoft co-founder now argues that what he called the "doomsday view of climate change" has caused the climate community to focus too heavily on near-term emissions goals and divert resources from addressing poverty and disease in the world's poorest countries.

In a blog post, Gates wrote that climate change will have serious consequences but will not lead to humanity's demise. He acknowledges that some climate advocates will call him a hypocrite given his own carbon footprint and his 2021 book warning that climate change could be as deadly as COVID-19 by mid-century and five times as deadly by 2100.

The poorest countries receive less than 1% of rich countries' budgets at their highest level and that this share is shrinking as wealthy nations cut aid and low-income countries struggle with debt, he wrote. Rising temperatures are now inevitable and that the current consensus suggests Earth's average temperature will be between two and three degrees Celsius higher than 1850 levels by 2100.

Comment Why is there Daylight savings time? (Score 2) 79

People who created the concept were not stupid. It is based on the fact that the earth is an oblate spheroid, and tilts on its axis, and rotates around the sun.

So at different times of the year, the day/night 24 hour cycle makes for differences in light and dark times.

The length of daylight at the equators does not change that much over the course of the year.

The length of daylight varies more and more as the latitude increases. Eventually, it reaches a point where there are months that the sun does not set, and months where it does not rise.

What does this lead to? People who live closer to the equator find the concept of DST/ST annoying and stupid because they are taking their situation, little difference between summer and winter daylight length.

The further north or south you go from the equator, Daylight Savings time makes more sense. Eventually the differences between summer and winter daylight become so extreme (think land of the midnight sun) that there is no compensation.

Daylight Savings time is a simple 1 hour shift back and forth to compensate for that.

Makes you wonder how the majority of the world which doesn't use DST manages to cope.

Japan should have at least two, China should have 3-4, Western Europe should be 2-3, yet they all get by with one.

Automatic changes are nice, as long as the calculation of the date and the time it happens never changes. Even within the EU, the switch over time isn't consistent - some countries are 1AM, some are 2AM, some are 3AM.

The rank and file Left in America is motivated by violent envy. They are taught this in our public schools, reinforced in media, and encouraged by their self-serving leadership, who crave power and control. This is a Marxism strategy, plain on its face.

Now watch the useful idiots try and refute history and fact. Or employ ad hominem attacks, wailing 'you $$@&^@ l' or whatever. They are lost in their hate. Cannot be reached.

Marxism and its hellish offspring, communism, kind of sounds nice until you see how the incorrect assumptions at its base end up making for unprecedented human misery.

I have long said that pragmatism - which is based on demonstrable success, and adoption of what works - can take snippets from other 'isms, but never try to adopt a pure 'ism, be it communism, socialism, capitalism, libertarianism.

So here in the land so many hate, we have a lot of capitalism, a fair amount of socialism, snippets of libertarianism, and it largely works.

I dare say that listening to far left academic activists, and the abandonment of core constituents went a long way towards the shellacking the Democrats took in 2024. They need to return to more sane roots. A viable party cannot be maintained when it is inherently misandric in nature, and ignores basic science like biology. The margins of victory are too slim to cast out working class people, and men in general. You aren't going to win elections when your ideological head is Taylor Swift. Nothing personal against Taylor - she's just an entertainer deep in pop culture.

People laugh at this sort of thing, but $50 a week for 30 years is $78,000. If you got an 8% return on that money (and over the last 30 years you would have had to work pretty hard not to get that) you would end up with $325,593, with $247,593 of investment returns. Not to mention the fact that if you are having trouble making rent you probably should steer away from spending 10% of your rent bill having food delivered to your house.

Do you know why people laugh at that kind of reasoning. Because it's so laughably wrong.

First things first, it's not a zero sum game. That money you're spending on eating out is still going to be spent on food, in part or in whole if you don't eat out. So at best you're not getting the whole lot back. Also the fact you had to extrapolate that over 30 years shows that it is a false economy. How much is inflation going to affect $50 over 30 years? Inflation alone over the last 30 years tells me that it's worth half as much, before adjusting for the rising cost of living. My first professional salary is less than minimum wage in Australia now days and that was only 20 years ago.

Secondly, you won't get a decent house for $78K today, let alone in 30 years when you've saved up that amount.

Thinking that you're going to make money by counting coppers is a total false economy, so much so that we have a saying for it in the UK, "penny wise, pound foolish". There's no point in being careful by cutting out small amounts when your rent is 10 times that. What you need to do to get ahead is to reduce your big costs. Cutting $50 a week from your rent is going to get better returns than trying to cut $50 from your food bill just because you'll realise the full amount, unfortunately society is stacked towards the land leaches.

If anything, I'd say the biggest problems people have these days are falling into credit and loyalty scheme traps.

Loyalty schemes where you spend money at the Fart store to get Fart points on you Fart card that you can redeem to get Fart flights, however it ends up being a false economy because the amount you're spending peicemeal is less, then paying additional taxes and fees is more than saving and buying your holiday outright. However the system is gamified so that people don't see the forest for the trees ("your Fart points are expiring", "you only need 100,000 more Fart points", ad nauseum).

Credit is far more insidious because it encourages people to spend beyond their means. The idea that you treat your credit card as cash, put everything on credit and then use your entire salary to pay it off each month means that you're one bad financial situation away from destitution. This has also become gamified and sadly people have fallen for the idea that banks are giving you something for free... people actually think they've "beaten" the bank with "cashback" and other schemes (erm. for those wanting to argue the bank takes it's money from the merchant and gives you a pittance back to keep you giving them more money via credit). When I was a lad, saying you lived "payday to payday" was a sign that you were in dire straights as it meant you weren't able to put money away for luxuries or unexpected bills. Now it's a sign that you're doing well as most people are living "debt repayment to debt repayment" and it will just take one disruption before they start losing things. This has become so normalised that being a net saver like me makes you an oddity.
