I think air transport and oceanic shipping will probably still take time owing to energy density concerns, but there are electric trucks already (with trials of roadside charging rails that can actively charge during driving), and for a large part of the world, electrified trains are the norm. It's a uniquely US problem that rail isn't electrified, even other major OECD countries are above 50% if not more, while in places like India it is almost 100% electrified railway (one of the largest networks in the world).

What is the "frontier" in EVs that Chinese automakers are yet to achieve? And what automaker is at this so called frontier?

There are variants and flavours of this already at smaller scales like https://en.wikipedia.org/wiki/CalPERS?wprov=sfla1

But the US in general hates "state owned enterprises" in the form that China has.

Fundamental research shows progress on timescales that are incompatible with most "free market" timelines, i.e. the stock market does not want a company to spend 10 years developing the science for something that only pans out after that time period and vastly prefers short term success.

Not all high schools but the US has some schools which allow you to take very advanced material / even get a head start on your college credits.

Renting a 2b2b in the middle of Manhattan probably costs 100k a year, but that is very far from a "moderate-cost area".

Why would it be consistent with the scientific mainstream? Unless there's evidence that scientific reports and material are specifically up-weighted during training and prioritised somehow, whatever an LLM says will be only consistent with its training material, which could have any proportion of fake articles, Reddit posts, Quora responses, encyclopedia pages and joke blogs

Tangentially related to the idea of "apply a random rotation matrix" is one where you apply a random matrix to a set of points to preserve distances between them but transform them into a lower dimensional space. This is captured by the JL Lemma [1].

They also sell/have sold the Arya, the Sundara, and the Ananda.

It has more to do with the nature of the industry and firm. If your TC yearly is all cash and exceeds 500k, asking 100k of that as buy in is not too different from being granted stock options as an outcome. They could just reduce your TC by 100k one year and replace it with equity in the pool.

What continent contains Iran, Syria and (as the other comment pointed out) North Korea?

The "mass market" in almost every country outside of NA is already adopting EVs, and a large part of that has been Chinese cars which aren't sold in the US due to protectionism and regulations. Take a look at EV adoption across EU or Asia or anywhere else really (BYD in Brazil for example), and you'll see the same story everywhere. It is pretty much a NA centric perspective that "EVs aren't there yet" cause the definition of "there" is bulky pickup trucks with 1000 mi range.

It exists in the US as well (Zelle), except due to the super high number of banks, not all will have feature parity / have it enabled. The major banks like Chase support QR code scanning for instant transfers, smaller ones might require a phone number or email input via keyboard.

Is it clear if it uses the rotors in flight for lift or for forward movement? I think it would be wrong to call it a helicopter if the only time the rotors provided active lift was during take off / landing. There are fighter aircraft which fire thrusters downwards to achieve VTOL, but calling them rockets would be funny.

There is no consistent scale on that graph, so any local maxima of reports received would look similar to any other.

This was a historic period for low rates, but rates have been higher and have been changed faster before, for example during the late 70s / 80s. It went from 4-5% to nearly 20% over the span of a couple of years.

Data point of just 1, but even in a small college town in the Midwest US, 50% or more counters at the grocery stores I've visited have been self checkout. Some places are almost entirely self checkout, to the point where if you need assistance it's hard to find an actual person employed by the store.

Venture Capital and Hedge Funds are similar in the sense of "they both invest money and try to make superior returns". Just like all software is similar since "it uses computation to do useful stuff".

Venture Capital firms rely a lot more on deal flow and network effects. Their focus is usually on early stage private financing. There are certainly hedge funds which also do similar investing, but by and large they don't play a role during the investing process and largely work with public securities and other instruments. This is also why VC and PE industries tend to hire from B schools, and look for backgrounds very different from hedge funds which by and large tend to pick students from more quantitative or scientific disciplines.

That global persistence model across executions is very fascinating. If you don't mind, could you explain what line of work this is and how it helps the use case? I have encountered similar concepts at my old job in a bank, where programs could save global variables in "containers" (predates docker IIRC) and then other programs could access this.

A lot of finance companies sponsor events / prizes like this simply as a means of advertising and PR. If you come across this prize as a math student, now XTX is in your head and maybe you'll look them up and decide to intern there. And 10m is a drop in the bucket for such goodwill and PR, especially because anyone who has the skills to win this can surely be hired and make them as much money.
