Hence, my question about reducing the cost of maglevs. China is pursuing low-speed maglevs that run about 100 mph and are much cheaper. http://www.xinhuanet.com/english/2020-12/15/c_139591288.htm Japan is pro

Listening to Americans discussing trains is painful. China built 25,000 miles of high-speed rail in the time the United States has built zero. Yes, I understand that it’ll never work in America. Now, can you just answer my question: what wo

No, it’s the bike shedding that people do. They can’t actually answer the question so they digress and discuss something else. I guess you wanna talk about property rights?

Acela between NY and Boston is great. Taken it several times. However, if you do the math, Acela averages about 85 mph.

My question is, what would it take to reduce the cost of maglev trains. China has tried, but they are expensive. Japan is building an expensive maglev over the next couple decades.

I guess you could just answer my question instead of digressing. Trains do compete with planes. Consider San Francisco to Los Angeles, for example. That’s about 9 million people a year who fly? It’s only 400 miles. New York to Boston. Wash

What would it take to reduce the cost of maglev trains? Perhaps 300 mph trains would be enough to convince Americans to take a train. UPDATE Just answer my question instead of trying to explain that people won’t take trains.

With all the money that goes into weapons systems, it’s only going to be a decade before we have jets, tanks, artillery, etc that are all (semi)automated. Rather than expensive jets and tanks, swarms of cheaper robotic systems are going to

I see that it was discussed at the time. I was referring to the many posts that I see about Ukraine with few upvotes. The ones that seem to get upvoted are about Elon Musk or Starlink. At any rate, I suppose if someone says something tha

It’s not really supposed to be a forum to discuss current events. Reddit is probably a better forum. Ukraine/Russia usually doesn’t gather much traction.

By 2035, I would hope EVs are ready for everyone. China is pushing EVs, and they are the largest car market. Hopefully, they get us past the tipping point on improved and affordable EV’s.

No one said “throw money at it mindlessly“. I said “fund more real medical research” I’m a little busy to explain it for the 100th time. Can you do a little research instead of putting words in my mouth? There was a time when scientists tho

How about we simply fund more real medical research so we can cure all those diseases that you might eventually get?

Sort of an absurd thing to say. However, it’s repeated all the time, and in every generation in some form. One really has nothing to do with the other. If we could educate people at a younger age so they understand this, maybe we can make

“My hope is that Apple doesn't try to hurry out, say, a MacBook Air M3” Seriously? Drop an M3 in there as soon as it’s ready. Also, Apple still sells 8GB machines with a $200 upgrade to 16GB. Moore’s Law might be dead but we shouldn’t

Training can take hours, days, weeks, or months. Doesn’t the inference part only require seconds? Since it requires a fraction of the computation , can’t CPU’s be optimized for that? A few matrix multiplications

Yes, and there’s a lag effect so the temperature will still increase for years after that. However, to be clear, it’s unlikely we get to net zero in 27 years. We haven’t reached any of our goals so far and the goals only get more difficult
