Good on this kid for going to such lengths to verify his hypothesis and show a serious weakness in railway infrastructure. I hope he goes on to become a serious railway enthusiast and advocate for safe, efficient rail.

However, there are way too many factors in the number of derailments and safety incidents in US rail operations to pin them down to this one issue. Once the major operators embarked on a journey to squeeze more and more money out of the business, a lot of things happened. Trains became longer - excessively so. Used to be that a train 1.4 miles long was considered massive. These days they are the norm. Can you imagine a train so long that, in hilly terrain, sections of it are being dragged uphill while other sections are pushing downhill?

Reductions in staff, motive power fleets and maintenance have led to trains being badly composed, with loads being distributed in a less than optimal way. An old railway man once told me that the only time he broke a train was when he, in a rush and under pressure, agreed to attach a rake of fully loaded freight cars to the end of a train of empties. Unequal load distribution played a role in a number major derailment incidents, among them a derailment in Hyndman, PA, which required the town to be evacuated for several days.

ProPublica have a series of articles regarding rail safety, and specifically one about the dangers of long trains. So while the worn out springs certainly don’t help, they are only one of many things that are impacting rail safety, and probably not even the lowest hanging fruit.

SSDs were relatively new in 2010, and priced accordingly. Now it’s just about increasing sizes and (hopefully) reliability. I just don’t think that all of a sudden we’ll have huge cheap SSDs - people are used to a certain price point and manufacturers will take advantage of that.

The prices will stay the same. Manufacturers will just make more profit.

Equally then, the nuclear disasters shouldn’t count, right?

Deaths from an accident at an active nuclear power plant are not the same as deaths caused by a burst dam that was originally intended to produce electricity one day, but has never produced any. Especially if you call the statistic ‘Deaths per unit of electricity production’. At the time of the accident, it was just a dam, construction of any hydroelectric facilities was nowhere near beginning, so calling it a ‘hydropower accident’ is highly debatable (probably as at least as debatable as calling nuclear ‘conventional’). Without the inclusion of those deaths, hydro would be shown to be even safer than nuclear, given that it has produced nearly twice as much electricity in the time span covered by those statistics, while having caused a similar number of deaths (if you continue to ignore the increased miner mortality, otherwise nuclear will look way worse). The article also does not cite how they determined the number of 171000 deaths, given that estimates for the Banqian dam failure range between 26000 and 240000. The author mentions (but does not cite) a paper by Benjamin Sovacool from 2016, which analyzes the deaths caused by different forms of energy but, crucially, omits the Banqian dam death toll. I will try to get hold of that paper to see the reasoning, but I suspect it may align with mine.

How do you assume it’s ignoring their increased mortality?

The article makes zero mention of any such thing, and the section about how the deaths are calculated (footnote 3 in this section) only calls out the deaths from Chernobyl and Fukushima. Direct quote from the footnote:

Nuclear = I have calculated these figures based on the assumption of 433 deaths from Chernobyl and 2,314 from Fukushima. These figures are based on the most recent estimates from UNSCEAR and the Government of Japan. In a related article, I detail where these figures come from.

No mention at all of any other deaths or causes of death, nothing whatsoever. It’s the deaths from two nuclear accidents, that’s all. The figures from the cited study alone would multiply the number of nuclear deaths in this statistic. What’s worse, the author has published another article on nuclear energy which essentially comes to the exact same conclusions. But if you include deaths from a burst dam that has never produced electricity (but was planned to do so eventually), then you must include deaths among people who mine the material destined to produce electricity in a nuclear plant.

To me it simply looks like the author of this article is highly biased towards nuclear, and has done very selective homework.

Edit: It’s also the cleanest and nearly the safest source of energy, including the disasters. https://ourworldindata.org/safest-sources-of-energy

I love how the ‘Death rates per unit of electricity production’ graphic highlights deaths from a 1975 dam break in China, therefore making hydro seem less safe than nuclear, when the dam in question up to that point hadn’t produced a single megawatt of electricity (and by the looks of it, still hasn’t to this day). At the same time it appears to conveniently ignore the increased mortality among uranium miners.

Nuclear falls under ‘conventional’ - the PWR design of TMI is one of the oldest and most common types of nuclear reactor. It’s just another way of creating steam to drive a turbine which then generates electricity.

Nuclear is also anything but clean. People love to call nuclear ‘clean’ because its low in emissions, but that’s ignoring the requirement for either safe storage of radioactive material or reprocessing thereof, as well as the emission of radioactivity in the water cycled through the reactor.

Three Mile Island is the epitome of

conventional dirty energy

It doesn’t make financial sense to build new nuclear power plants. They’re hugely expensive and such projects routinely run well over time as well as budget. If it did make sense, Microsoft would be building them, instead of reviving the site of one of the worst nuclear disasters in the US. Thing is, they want lots of power, and they want it yesterday. By the time you can build a new nuclear plant to satisfy these needs, AI will have run its course and big tech will be on to the next scam.

But hey, why pay attention to such nuances?

Sure, training data selection impacts the output. If you feed an AI nothing but anime, the images it produces will look like anime. If all it knows is K-pop, then the music it puts out will sound like K-pop. Tweaking a computational process through selective input is not the same as a human being actively absorbing stimuli and forming their own, unique response.

AI doesn’t have an innate taste or feeling for what it likes. It won’t walk into a second hand CD store, browse the boxes, find something that’s intriguing and check it out. It won’t go for a walk and think “I want to take a photo of that tree there in the open field”. It won’t see or hear a piece of art and think “I’d like to be learn how to paint/write/play an instrument like that”. And it will never make art for the sake of making art, for the pure enjoyment that is the process of creating something, irrespective of who wants to see or hear the result. All it is designed to do is regurgitate an intersection of what it knows that best suits the parameters of a given request (aka prompt). Actively learning, experimenting, practicing techniques, trying to emulate specific techniques of someone else - making art for the sake of making art - is a key component to humans learning from others and being influenced by others.

So the process of human learning and influencing, and the selective feeding of data to an AI to ‘tune’ its output are entirely different things that cannot and should not be compared.

Generative AI is not ‘influenced’ by other people’s work the way humans are. A human musician might spend years covering songs they like and copying or emulating the style, until they find their own style, which may or may not be a blend of their influences, but crucially, they will usually add something. AI does not do that. The idea that AI functions the same as human artists, by absorbing influences and producing their own result, is not only fundamentally false, it is dangerously misleading. To portray it as ‘not unethical’ is even more misleading.

Re 1, 3 and 5, maybe it is upon the AI projects to stop providing shiny solutions looking for a problem they could solve, and properly engaging with potential customers and stakeholders to get a clear understanding of the problems that need solving.

This was precisely the context of a conversation I had at work yesterday. Some of our product managers attended a conference that was rife with AI stuff, and a customer rep actually took to the stage and said ‘I have no need for any of that because none of it helps me solve the problems I need to solve.’

Last time I checked, on iOS it didn’t have either.

Edit: just checked, the iOS version still doesn’t have downloads and does not support casting to Chromecast.
