No. Size is the dominant factor. Lifespan and what stages of fusion it undergoes are dependent on its size. The more massive the star, the shorter its life span. Red dwarf stars can live for trillions of years, but massive stars may live less than a billion years.

Notice that haiguise wrote "at the core temperature of the Sun." A more massive star has a higher core temperature, and thus haiguise's sentence about fusion rates would no longer apply. Fusion rates are faster at higher temperatures, and that's why more massive stars burn out faster. Notice haiguise wrote "T^4" and "T^20." Our sun is roughly 5000K. Massive stars can exceed 10000K. At twice the temperature, T^4 and T^20 imply 16x and 1,048,576x fusion rates, respectively.

Edited to add: Wikipedia has an HR diagram with labels showing lifespans for stars at different temperatures: https://commons.wikimedia.org/wiki/File:Hertzsprung-Russel_S....

But what is the effect on lifetime of not having any CNO present? If a present-day massive star would have a lifetime of 10 million years, how long would it live if it was a population III star with no CNO?

My understanding of the evolution of Earth flora is that prior to plants being green, the dominant plant life was red (think of red algae blooms) and that the current dominant green plant life likely evolved to use different photons along the EM spectrum where there was less competition.

Funny enough as I understand visible light and the EMR spectrum there is no "green" (color/wave length/energy) rather the color green is a construct originating not in the light spectrum but in the mind of the observer.

There is a range of wavelengths of light that humans perceive as green. The same is true for every color that is part of the rainbow. In contrast, the "pure purples" do not appear in the rainbow, and there is no single wavelength of light that humans perceive as purple (it requires red light plus blue light).

I’ve never understood that number. I’ve read that modern humans have been around for 200k years, but I’m supposed to believe that for 3/4 of that time they stayed in Africa? BS. Maybe proof hasn’t been found, yet. But we know from our own experience that modern humans love to explore. I don’t believe that love of travel and adventure and exploration is cultural. Our modern ancestors would’ve been exploring out of Africa long before 50kya.

There's an important distinction between anatomically modern humans and behaviorally modern humans. Behaviorally modern humans were the ones that were able to migrate all over the world.

I remember someone suggesting using deliberately crude and hand-drawn looking UI elements in the demo. That communicates to non-technical users that it's just a prototype.

Something like https://wiredjs.com/ might work, if you are building a web-ui.

Fabulous idea. I will definitely use this for future early-stage demos.

“Intelligence is situational — there is no such thing as general intelligence. Your brain is one piece in a broader system which includes your body, your environment, other humans, and culture as a whole. […] Currently, our environment, not our brain, is acting as the bottleneck to our intelligence.”

“Human intelligence is largely externalized, contained not in our brain but in our civilization. We are our tools — our brains are modules in a cognitive system much larger than ourselves. A system that is already self-improving, and has been for a long time.”

“Recursively self-improving systems, because of contingent bottlenecks, diminishing returns, and counter-reactions […], cannot achieve exponential progress in practice. Empirically, they tend to display linear or sigmoidal improvement.”

“Recursive intelligence expansion is already happening — at the level of our civilization. It will keep happening in the age of AI, and it progresses at a roughly linear pace.“

Moore's Law. Use computers to make better computers. Exponential growth over more than 7 orders of magnitude and, although the growth rate is slowing, it hasn't run out of steam yet.

If AI eventually exhibits anywhere near that level of recursive self-improvement, godlike superintelligences lie in our future.

I always come back to the analogy of nearsightedness. You can be a little bit nearsighted, or a lot nearsighted. It’s a continuum. It isn’t even precisely a problem to be nearsighted, in theory. It’s just a problem in our society which is designed around being able to see things that are far away (e.g. road signs.) Glasses aren’t technically a treatment for an illness; they’re an optional prosthesis—a “body mod” in the cyberpunk sense. But there’s no stigma to getting them (nor should there be); and anyone who has any degree of nearsightedness has no reason not to get them.

Perhaps a potential solution is POW based registration, registration is slow and CPU heavy. I don't think it's likely there is going to be a perfect solution to this and might be that it's better to slow down bad users and make it expensive to ban evade.

That's a very interesting idea, though it wouldn't significantly affect people with vast resources such as botnet owners, corporations, and governments. It would certainly slow down the garden-variety troll, however the determined troll would just keep a core burning to create a steady stream of sock puppet accounts.

My bet is that it was always evil, no one noticed because they were distracted by the amazing customer focus and service.

Google may have touted the "do no evil" matra, but looking back, their plan was always to look over your shoulder. Nothing Google did was ever altruistic, and I think Amazon was and is the same way.

While Larry and Sergei were running Google, the company often (though not necessarily always) chose doing what was right over a more profitable wrong. A specific example was when they discovered the Chinese government was behind a major security breach targeting dissidents, they refused to continue to comply with Chinese censorship requirements.

However, as the founders lost interest in the day-to-day operation of the company, any pretense of being more than just another soulless profit machine was discarded.
