that's a very impressive demo, I have never seen a robot move so smoothly before.

My copy of Breakneck arrived a few days ago and I'm rushing through the book, hard to put down, highly recommended


and SpaceX has been a major buyer of Cybertrucks


and Tesla is valued at over 21x more than GM


Sorry, I lost the thread - GM looks twice as profitable, the same profit on half the revenue

How does that justify Tesla's valuation?

Is it based on the idea that the margin can be improved?


> Sorry, I lost the thread - GM looks twice as profitable

You got it reversed.

For Q3'2025, GM net income $1.3B on $48B revenue (down 0.3% YoY). Tesla, in contrast, generated $1.5B income on $28B revenue (up 12% YoY).

GM's income was down 56.6% while Tesla's was down 37%.

GM had higher operating income than Tesla, however. Explained by Tesla's more aggressive investment in R&D and AI.


Ah, got it now, thanks


It's based on "Tesla shareholders want the stock to live in a parallel universe".


there was a rush to buy electric cars in the US for as long as the $7500 incentive was in place, so the Q3 2025 number if inflated; it's a pull forward effect.

Sales have been flat for 3 years and the delivery numbers in Europe are catastrophic

on a fully diluted basis, the market cap is above $1.6tn, so at a PE of 20, they'd have to generate something like $80bn in profit per year - hard to do in an industry that is as brutally competitive and low margin as passenger cars.


Not to mention China heavily subsidizing BYD.


It's a myth that China heavily subsidises its EV industry. See e.g. this Bloomberg article titled "China Can't Cut EV Subsidies It Isn't Paying": https://archive.ph/5olix


> It's a myth that China heavily subsidises its EV industry.

We must live in parallel universes.

From 2009 to 2022, China offered national purchase subsidies for EV buyers. Peak subsidies: ¥40,000–60,000 per vehicle (~$6k–9k). Combined with local subsidies, some buyers paid 30–40% less than market cost. These subsidies were phased down and formally ended in 2022, but the industry had already reached massive scale.

This policy alone created the world’s largest EV market.

Even after direct subsidies ended, China continues to provide: EV purchase tax exemptions (10% tax waived), extended through 2027.

China provides EV manufacturers with: Cheap or free land, Low-interest or state-directed loans, Preferential electricity pricing, Grants for factories, R&D, and tooling, State-backed battery supply chains.

China strategically subsidized battery production: CATL, BYD, and others received R&D grants, Guaranteed demand, Export financing.

China now controls ~75% of global lithium refining and ~80% of battery cell manufacturing.

This dramatically lowers EV costs versus foreign competitors.

No value judgement about subsidizing, but to say it is a myth that China has and continues to subsidize their EV industry is false.


From the article that you added in addition to the statements below, I don't think BYD is succeeding only by subsidies. I'm solely stating that they're heavily subsidized. China has a strategy where most western nations don't appear to have one.

----

It might be tempting when one has been asleep at the wheel to chalk up the rise of Chinese carmakers led by BYD to unfair subsidies, especially since leaders in Washington and Brussels have done so. No doubt, China is far from a free, fair and open market. The scale and pervasiveness of corporate subsidies at the federal and local level far exceed what other market-based economies offer.

> China has a strategy where most western nations don't appear to have one.

EVs were subsidised in the west, e.g. in California (#4 "country" by GDP), Norway, and US tax incentives - which have gone away after the Trump anti-renewables Bill of 2025. MRSPs for EVs were slashed after September 2025 due to the loss of this subsidy, and 2 months later Ford cancelled it's electric F-150 program.


How come BYD’s stock price is essentially flat?


> How come BYD’s stock price is essentially flat?

Their profit growth has slowed (significant drops in profit YoY). Even revenue has dropped in some quarters.

Investors had very high growth expectations given their past rapid expansion, but investors now see only moderate growth.

Intense competition and pricing pressure.

China EV market is slowing. Overcapacity is emerging over the sector and govt subsidies are softening.

Finally, global macro and sentiment towards Chinese stocks is cautious.


We often think market is rational but it is not. If it is, then BYD would be priced like Tesla, and Tesla would have been priced like BYD.


Lately I've realized that "Chinese subsidies" are psychologically useful for people outside China to believe in, as cope to handwave away their own failing industries. Solar panels aren't really subsidized in China either.


China has a plan. It subsidizes technology that it sees as important. There's nothing wrong with that per se.

It'd like me saying that Barry Bonds only won the home run records because he used steroids. It wasn't entirely the steroids but I'm sure they certainly didn't hurt.


> There's nothing wrong with that per se.

Contemporary western capitalism would disagree. You can never subsidize technology cleanly, only an organization of people working with that technology. We would usually denounce that as "picking winners" in our system.


Solar panels were explicitly targeted as a central planning directive and so manufacturers received many direct and indirect subsidies lol, these are well known facts. We should be subsidizing solar energy in the west too, as we've subsidized the oil and gas industries. To say China haven't subsidized solar is just not being real.


Currently Chinese are competitive because because developers work on burnout level intensity and workers have no life but factory around the clock.

Of course, the salaries and working conditions are going up in China while west is eroding worker rights as fast as we can. One the factories will come back here simply because we'll end up cheaper. Don't buy solar made by Xinjiang forced labor, by solar panels made by illegal immigrant prison labor!


there are around 140 EV companies in china competing very aggressively, they have excess capacity and are flooding the world market with cheap EVs, tough for Tesla to have a healthy margin in that environment


BYD's exports are not subsidized, and are, in fact, a massive cash cow for the firm.

They are also way cheaper and at comparable quality to western cars.


It’s also Americans realized how inconvenient electric cars are. I take a fair amount of road trips. I don’t have the time to wait 30 minutes minimum to charge. And if there’s a line it’s even worse. And in the winter the heater reduces the distance a ton. It just isn’t practical


I’ve found the charging to be a non issue. It’s basically timed with bathroom / food breaks.


I have found charging to be a huge issue, and so has the majority of Americans (clearly). But why let facts interrupt an HN circle jerk?


I personally have taken several road trips (1000+ miles) with an EV across the United States and have not found charging to be a "huge issue".

But I (clearly) must be wrong, sorry to disagree with the spokesman of America.


How many hundreds of miles do you typically drive at a time?


what are some historical examples of bubbles that didn't pop?


Since this is HN, I'll go with the most obvious: Software development. Unsustainable, speculative growth through the COVID-19 period, but on the other side relatively slow decline.


This is the perfect example of people who constantly cried that it is a bubble but it wasn’t.


Nobody pays attention to things aligned to the fundamentals. When people are crying that there is a bubble, it is a bubble. Plain and simple.

We know for certain it was a bubble as non-bubbles have sustainable growth. As all the software developers now struggling to find work will be happy to tell you, the growth wasn't sustainable. The proof is in the pudding.


How do you prove that software development is a bubble?

Stock prices are at all time high and continuously growing.


> How do you prove that software development is a bubble?

By looking at the software development market. How else would you do it? Salaries rose sharply from 2020-2023, but then plateaued and are now starting to decline. Slowly, however. It did not crash. It ticks the boxes: Rapid price appreciation, speculation, a disconnect from fundamentals, widespread media attention, and an eventual correction.

> Stock prices are at all time high and continuously growing.

If we're sharing random facts: Global average temperature is also at an all time high and continuously increasing.


1. the labour market has not much to do with whether it is a bubble or not

2. definition of bubble is that the market cap must precipitously reduce, which it hasn't.


> the labour market has not much to do with whether it is a bubble or not

How can the very market we're talking about not indicate whether there is a bubble in that market or not? Do you think we should be looking at the price of soybeans instead?

> definition of bubble is that the market cap must precipitously reduce, which it hasn't.

Incorrect. It has, just not by very much. Which isn't surprising as we already established that there wasn't a crash.


What is your definition of bubble then? If not by market cap?


Why read comments in isolation? We already went over this:

- Rapid price appreciation

- Speculation

- A disconnect from fundamentals

- Widespread media attention

- An eventual correction

If market cap, how do you explain housing bubbles? Market cap is not applicable to housing.


of course market cap of housing went down! individual houses fell down in price.

that didn't happen for tech stocks. you are making your own definitions of bubble - the sufficient thing to happen is for the market cap to go down precipetously which it didnt.


> of course market cap of housing went down! individual houses fell down in price.

Traditionally, market cap only refers to companies. I accept your pet definition that includes any kind of market, but then we can apply it to the software development market just the same. Individual software developers have fallen in price. There was not a significant drop, but a slow decline.

> that didn't happen for tech stocks.

Nor gold. But what does that have to do with the software development market? Are you under the impression that stock certificates write code?



you are giving a new meaning to the term "PR stunt"


Or at least swapping out something else for the first two letters of "stunt"


i have to say I'm a little disgusted by these statements. LLMs are useful for many problems, but is there really a conceivable path of them making progress into fighting the countless cancers tormenting humanity?


My framing device: if you had LLMs in the 1500s, how would that help Copernicus determine the orbits of the planets? Maybe through dumb chance, but creating a well reasoned model of the universe required new observations and the ability to interpret the data from a different point of view.


All the 1500s and earlier data that such an LLM would have to have been trained on would lead to an LLM that wouldn’t ever suggest a heliocentric solar system. That LLM might even say he was heretical or refuse to give an answer to anything that led to it saying that the earth wasn’t the centre of the universe. So no help at all.


More likely the LLM would condescendingly tell him that he was wrong and that the earth was clearly at the centre of the universe.


Depending on the time of creation, it might be impossible for the LLM NOT to tell him he's wrong and the earth is the center of the universe.


Interesting framing. Although I assume all the observations had been done already. It was more about being bold enough to investigate a line of thought that wasn't obvious or popular at the time and proving it convincingly.

They already had many "explanations" and models for why the planets were seemingly moving back and forth in the sky during the year. Their models were more complicated than necessary simply because they didn't want to consider the different premise.


Without those sorts of revolutionary claims, would they still be receiving enough funding to keep the lights on?


are you paying them enough to have profitable unit economics? How hard would it be for you to switch from one provider to another?


there's some lock-in for both chatgpt (the history and natural chat personalization feature is super useful) and with Cursor I'm fully invested in the IDE experience.

The lie is that LLMs are the product itself rather than the endless integration opportunities via APIs and online services.
