They have existed far longer than LLms, and kill tens of thousands of Americans every year.
Fentanyl is the best example. Any chemistry graduate can figure out how to manufacture it. Used by China as a Chemical weapon against the American public.
The prices are really quite good for a country where everything is so expensive. Only 3000 for an aluminium rail car. Probably the scrap metal value is higher than 3000, although you could spend far more than 3000 transporting it to the scrap yard.
That last bit is the killer, from their website,machine translated:
"The buyer is responsible for organizing loading, transport, customs clearance, etc., as well as any associated costs. The vehicles are available immediately and are delivered uncleaned from the storage location (Bonfol train station). "
It's always the same deal with rail stuff. You can find old cars for cheap (locomotives not so much, they tend to be worth a lot more than scrap value in spares). The catch is always the transport. I've seen this more than a time or two on rail enthusiast forums. Somebody buys an old caboose or boxcar to just drop behind their house for a couple grand.... and then discovers it's gonna cost at least 3-4x that to move even a few miles. Usually need a heavy duty low boy trailer (https://heavyhaulers.com/blog/wp-content/uploads/2021/01/low...) and a fairly heavy duty crane at both ends.
Maybe, but AI models are better at writing python and JS than any other language. Probably because they are the most common and thus had the most code available for training.
I never found myself in fear that I’m doing something unoriginal. However, I do find myself worrying I'm doing something a better resourced competitor is also working on.
Most things worth doing are actually quite obvious. The determining factor in success is execution, not originality.
ETCS level 2 can increase rail capacity by orders of magnitude without laying any new track. You can have multiple trains following each other separated by stopping distance instead of having to separate trains between trackside signals.
I don't think so, faster trains are overtaking slower trains. There is simply not enough space between the station to overtake without having an acceleration that would damage the trains or the tracks. For example in western switzerland the maximal train speed for the fastest trains are ~130 Km/h while the same train can go up to 200 in some swiss-german part, only due to more congestion on the western part.
Trains cannot be bigger, some of them are already too big for the smaller train station and in case of rerouting / unexpected stop this causes issue. You cannot make them higher too.
You could get ride of the smaller train , only allowing big city to survive
or decrease the commodity traffic
or increase the rail network
or increase the train station (more tracks allowing to overtake there, and have bigger trains)
There is no easy solution otherwise it would have been done.
The data/facts disagree with you. In a low birth rate society a constant influx of new tax payers is required. Without it you end up with decades of stagnation like Japan.
1) Populations are their most expensive at their oldest age and each subsequent generation is smaller and needs to pay for an old generation larger than their own
2) infrastructure and many of the things a government provides is not scalable down and up. A road is not (much) cheaper to maintain because less people drive on it
This sounds like a strong argument for having a stable cap. It's not a total immigration ban and would freeze population at a steady state. This makes all of the boom and bust problems easier, not worse
