Surely arm is a better choice?

Depends on what criteria you use for "better". ARM is surely more advanced technologically, but RISC-V may be a more future-proof decision as you're not necessarily tied in to one company that may change their licensing costs in the future.

Mandatory Light/Dark side of the force reference.

ARM will get you power faster.

But in the long run, RISC-V will be the most powerful.

This is it. China might be authoritarian, but it's acting way less eratic than the US right now.

"right now" being the key phrase here. On what length of time due you judge stability? The last 75 years or so in China... well amoung other things they killed over 50 million of their own people with a man made famine. The question is if the institutions that produced USA can hold. China on the other hand lacks the self correcting mechanisms that USA has built in.

50 million ?

according to someone's research[1]:

here are some civilian deaths within china:

- land reform killed 1-4.7 million

- campaign to suppress counterrevolutionaries killed 712k-2mm

- three-anti and five-anti campaigns killed at least 100k

- sufan movement killed ~53k

- anti-rightist campaign killed 550k-2mm

- '59 tibetan uprising killed 87k

- violence in the great chinese famine killed 2.5mm

- socialist education movement killed 77k

- guanxi massacre killed 100-150k

- inner mongolia incident killed 15-100k

- yangjiang massacre killed 3.5k

- daoxian massacre killed 9k

- ruijin massacre killed 1k

- zhao jianmin spy case killed 17k

- shadian incident killed 1.6k

- tiananmen square protests & massacre killed 200-10k

so it's 52.5mm!

that's huge!

The US is extremely chaotic and unpredictable. China is fairly stable and predictable.

Most authoritarian states are 'stable and predictable'. When you meet a lion on the savannah the beast is stable and predictable in that it will most likely try to eat you unless it isn't hungry. Step on a snake and the outcome is stable and predictable in that you will get bitten. It is good for Europe to learn to stand on its - our - own legs, to become less dependent on the USA for territorial defence and probably…

> So, 'Europe first' in the sense that the ideas which formed the continent are worth defending and so are people who subscribe to those ideas no matter where they come from. Those who want to get rid of these ideas to replace them with their own intolerant society - whether that be an islamic caliphate or a Chinese-style fascist [1] surveillance state - are not welcome. I realise this includes a number of EU bureaucrats who are enamoured of the latter system and I would be pleased to see these individuals removed from power, preferably by truly democratic means.

The US is not just erratic, it wouldn't be a stretch to call them hostile towards the EU right now.

That’s a pretty insane take that ignores decades of actual history.

You need to believe what your eyes are seeing.

Canadians are taking Trump's threats very seriously, as is Greenland, as is Panama, as is the EU. And for good reason.

Because RISC V results would be something the Europeans could produce? We are reliant on the US as only 2 companies can make the x86/64 chips. I don't think Europe would be completely against working with a US or Chinese company like Hi Five/Star Five, as long as we weren't dependent on them, and could pull ties if they abused their position of control.

> We are reliant on the US as only 2 companies can make the x86/64 chips. The x86-64 architecture is on its way out globally thanks to Arm. RISC V is not needed for decoupling from the US.

Arm is not a trustworthy partner.

Otherwise they would be more than happy to renegotiate chip licences if they feel that companies have overstepped.

Instead they publicly litigate and demand destruction of all designs.

If the goal is to decouple from the U.S., why would the EU want to collaborate with a totalitarian state like China?

The US is extremely chaotic and unpredictable. China is fairly stable and predictable.

Stable and predictable in supporting russian invasion in Europe.

You mean the history of enshittification by the monopolistic US companies with the lack of any regulation in their country? Also, forcing horrible IP laws on Europe. More details: https://pluralistic.net/2025/02/26/ursula-franklin/

And the history of NSA spying on the whole world, see PRISM.

> The US founding fathers included everyone in their vision, btw Of course many were only 3/5th included. And half the population weren’t included at all.

That’s not a fair or reasonable thing to point out given that few countries at that time gave slaves or women voting rights. The U.S. was one of the first majority White countries to give Black men voting rights in 1870, after France did some time in late 1700s. Haiti was the first country to give all people, regardless of race, voting rights in 1804. I agree that the U.S. was really late to enter into women’s suffra…

So the vision included a tiny minority of land owners.

General suffrage in 1789 was about 1 in 20 people, almost entirely white land owning men.

20 years later the vote was actually taken alway from many of the few black men who had it. White men still needed property. In parts of the US this property requirement lasted until the 1850s, and after that the requirement to be rich enough to pay taxes survived well into the 20th century.

I’m not criticising anything other than this idea that america was a government of the people by the people - at least until the 20th century.

> Axelera's chips follow a similar formula as other AI ASICs, such as Google's tensor processing units. The Dutch outfit's current silicon feature four accelerator cores, each with a matrix multiply-accumulate (MAC) unit, a RISC-V control core to make the accelerator programmable, and some digital signal processors which handle neural network activation functions.

This seems very focused on current architecture, which could be replaced with something more novel without the fundamental limits of matrix multiplication.
