Is this how the US falls behind? Missing technological improvements due to blind disagreements with Chinese/etc, combined with inability to update infrastructure? (Unclear how/why but datacenters being stood up so quickly seems like an exception to US’s bad construction)

In a word, yes. In a few words, yes that's the entire situation summary. No long term strategy exists for the entire country.

Earlier quoted context omitted.

What are the requirements of vehicles that drive across the border, like if a Canadian family is holidaying in Buffalo? If they're driving a BYD, do they get stopped at the border? What if they sold their BYD to a US family? Can it be registered and insured? I'd guess not, therefore it wouldn't get bought by a US resident in the first place.

Border-crosser here: Many Canadian-model-only vehicles are driven in the US by tourists and the like - you can bring it in for up to the year temporarily.

https://www.cbp.gov/trade/basic-import-export/importing-car

> Nonresidents may import a vehicle duty-free for personal use up to (1) one year if the vehicle is imported in conjunction with the owner's arrival. Vehicles imported under this provision that do not conform to U.S. safety and emission standards must be exported within one year and may not be sold in the U.S. There is no exemption or extension of the export requirements.

To actually legally permanently import the vehicle, you have to go through the rest of the onerous CBP requirements, validate safety standards, etc, etc - and that's when it becomes a true screwball and it'll never happen. But yes, I guarantee you'll see some BYDs running up and down the Northeast, and very likely spot them around Florida as snowbirds drag them down with them still. I think I'm even more likely in my position to see a BYD with red Ontario diplomat plates, now that I think about it...

My favorite oddball I've seen the most of is the Chevy Orlando MPV. https://en.wikipedia.org/wiki/Chevrolet_Orlando

For the majority of Americans, “the US falling behind” is not something they care about. The principal thing they care about is not whether the whole is ruined but whether they have an appropriate portion. An American would prefer that a field make 1 unit of rice if everyone got 1/n units. This is different from cultures where the preference is that you maximize your wellbeing (older America) so that if someone could…

Maybe. Agree that zero-sum thinking sucks. You gotta grow the pie. But. You also have to share the big pie.

In your example, the current crisis can be represented as:

A field exists and produces 1 unit.

A financial entity buys the field and applies unsustainable methods to increase production 100 units, keep 99.5 of them, distributes 0.5/n. People are pissed that they’re getting half of what they used to despite incredible productivity. The people elect a leader to fix the situation. The leader confronts the financial entity, and returns to the people with 4 units in their pocket and excuses.

Based on the figures here, they’re claiming around 400 miles of range added in 300 seconds (60% of the full 677 mile range); contrast this with around 100 seconds for a typical gas pump (8 gal/min) and typical efficiency (30 mpg). It suggests that you’d need around 5MW chargers to truly get to the speed of a gas pump.

On the other hand, 5 minutes is already a huge improvement over 15-30 minutes, and it’s fast enough to remove much of the friction of recharging an EV.

Really wish this kind of tech would come to North America…

This [0] is the actual (good) news, linked from the article. [0] https://www.techradar.com/vehicle-tech/hybrid-electric-vehic...

Neither article really explains how they are able to charge this fast, aside from “vertical integration” and slightly increased energy density in the battery design. No real details on the charging technology itself.

That’s a rather tall argument given that the US is currently experiencing historic income inequality [1].

I mean if you really think about it china already has or is on the verge of: - energy independence - ASML level microchip production - the SOTA of AI - citizens that accept surveilence and lack of privacy - strong local manufacturing - eastern world support - yuan recognized as a stable world currency But they do suffer from issues as well: - Aging population - Autocracy (or well, one party system) - Brain drain (bet…

> citizens that accept surveilence and lack of privacy

It's certainly not to China's extent, but is America really that opposed to surveillance and lack of privacy?

Yes, we tend to raise a huge stink when evidence of such comes to the surface.

But actions speak louder than words, and through our actions we already largely accept surveillance and a lack of privacy.

Everyday consumer apps are some of the worst offenders. Our social media apps listen to us, Amazon Ring doorbells are allegedly accessed by ICE (though Amazon denies it), Flock cameras abound (not to mention the fact they're poorly secured so who knows who else is watching other than the municipalities Flock contracts with), companies own much of our data and sell them to myriad unknown sources on a whim. There are too many examples to list.

No, it's not as severe as China. But we're certainly not trending in the right direction.

Data centers are (a) private not public and (b) throwing money at the problem on the assumption of being able to capture a significant chunk of all white collar incomes. And they're running into the public issues already, such as lack of large power transformer availability and noise complaints from trying to generate their own power.

But gas pumps / electric charging stations are also private.

Absolute garbage. Just stop and think for one second what kind of power delivery is required to do this and you will quickly realize that’s it’s not feasible anywhere other than as a demo.

not feasible yet, keep in mind we regularly transport tons of power in the form of gasoline - an absolutely massive (literally) chain of logistics

moving and storing electricity can vastly simplify the process and work like this will mature

It's how Europe falls behind, you mean. Why do they always get left out of the comparisons? Because they're so far behind anything it would be an insult to include them?

I think this is probably because Europe is considered part of "the West".
