Similarly, some bosses might believe that they can hire 100 cheap, unmotivated SWEs to replace Linus Torvalds or Fabrice Bellard and achieve something slightly worse. But in certain areas, it doesn't work like that.

It's funny that Google, Meta, TikTok, OnlyFans, PornHub, and many other lucrative businesses never open-source their core business software, and people just don't bother about it with that moral standard, simply because we don't need to pay for the service (paid by ads, actually). To me, that is the hypocrisy.

Joking aside, I also don't believe that maximum access to raw Internet data and its quantity is why some models are doing better than Google. It seems that these SoTA models gain more power from synthetic data and how they discard garbage.

Also, not sure why everyone forgets about it. People should have learned from the experience of the pandemic that the cutting-edge foundry nodes are not really the crucial ones, as being the bottleneck of industrial infrastructure. A delay of the next-gen iPhone or RTX gaming card isn't that catastrophic. But a shortage of embedded MCUs, which are actually fabricated by mature nodes, could stall the entire industrial base of a country.

This is only relevant to the compute productivity (how much useful work it can produce), but it's irrelevant to the heat dissipation problem. The energy income is fundamentally limited by the solar facing area (x 1361 W/m^2). So the energy output cannot exceed it, regardless useful signals or just waste heat. Even if we just put a stone there, the equilibrium temperature wouldn't be any better or worse.

Even for a simple sphere, if we give it different surface roughnesses on the sun-facing side and the "night" side, it can have dramatically different emissivity.

Given the solar constant 1361 W/m^2, you can calculate the temperature range based on the emissivity and absorptivity. With the right shape and “color”, the equilibrium temperature can be cooler than most people thought.

I suppose that a space data center powered 100% by solar is no different than this iron ball in principle.

>Heat radiation works better the higher the temperature?

The power output is proportional to T^4 according to the Stefan-Boltzmann law.

I guess the trick lies in the operating temperature and the geometry of the satellites.

I understand that these days, businesses and hobbyists just want to use free LLMs without paying subscriptions for economic motives, that is, either saving money or making money. They don't really care whether the source is truly available or not. They are just end users of a product, not open-source developers by any means.
