What do you think it feels like to be the best in the world in your field?

Must feel depressing. Because high intelligence comes with higher levels of nihilism and apathy. You inevitably realize how meaningless and futile everything is.

Just because some study says intelligent people are more likely to be depressed that doesn't mean every intelligent person is depressed.
I bet you choose to believe this because you're depressed and you want this to mean you're smart

I was wondering. The human brain or any earth-brain really probably had a common ancestor. They're all evolved on the same framework; That is a neural network.

Would the brains (if they have such things) of an alien species that evolved on a different planet be likely to be similar? Is the idea of a centralised neural network the only solution to the problem of cognition and learning?

Are there other architectures that would provide vastly different results?
How so? What would an Alien brain or equivalent learning/control organ behave/function like?

I believe its possible to simulate human neural networks on silicone for what it is worth.

If it has an input output system thats compatible with Real-Life.exe it can be made intelligent.

MEME

How come nothing intelligent ever came out of the millions of years reptiles and dinosaurs/birds had on this planet? Were we just incredibly lucky in the sense that everything just fell perfectly into place?

I'm not educated enough in this field (which is why I'm asking this question) so this might come off as incredibly stupid but was it because there wasn't enough variation in the global gene soup?

Because God just wanted one intelligent species on this planet and raptors were getting to uppity to leave around.

Probably a number of factors, including diet and basic anatomy. Birds can be pretty smart, just look up videos of corvids performing cognitive tests at the level of infants and chimps.

How close should a moving part be from another moving part be to be mostly frictionless and not grind or be too stuck?

In mm
.10th mm?
.05mm?

Do manufacturers even go to .05mm?

EXAMPLE-If this big circle you see is rotating how many micro mm should it be from its surrounding metal so it moves without friction catching it.

Do they plan on being able to recover the second stage at some point? That seems like it's still a pretty big cost per launch.
>>
>>8127663
Yes, but it might not happen until development of the methane raptor engine is completed.

>The broader Raptor concept "is a highly reusable methane staged-combustion engine that will power the next generation of SpaceX launch vehicles designed for the exploration and colonization of Mars". According to Elon Musk, this design will be able to achieve full reusability (all rocket stages) and, as a result, "a two order of magnitude reduction in the cost of spaceflight.

>Scientists in the US are trying to grow human organs inside pigs.
>They have injected human stem cells into pig embryos to produce human-pig embryos known as chimeras.
>Walter Low, professor in the department of neurosurgery, University of Minnesota, said pigs were an ideal "biological incubator" for growing human organs, and could potentially be used to create not just a pancreas but hearts, livers, kidneys, lungs and corneas.
>if the iPS cells were taken from a patient needing a transplant then these could be injected in a pig embryo which had the key genes deleted for creating the required organ, such as the liver: "The organ would be an exact genetic copy of your liver but a much younger and healthier version and you would not need to take immunosuppressive drugs which carry side-effects."
>These embryos have been allowed to develop for up to 62 days - the normal gestation period is around 114 days.
>Like the team in California, Prof Low said they were monitoring the effects on the pig brain: "With every organ we will look at what's happening in the brain and if we find that it's too human like, then we won't let those foetuses be born".
>In Greek mythology, chimeras were fire-breathing monsters composed of several animals - part lion, goat and snake. The scientific teams believe human-pig chimeras should look and behave like normal pigs except that one organ will be composed of human cells.

But of course, atheist-hippies ruin everything

>But organisations campaigning for an end to factory farming are dismayed at the thought of organ farms.
>Peter Stevenson, from Compassion in World Farming, told me: "I'm nervous about opening up a new source of animal suffering. Let's first get many more people to donate organs. If there is still a shortage after that, we can consider using pigs, but on the basis that we eat less meat so that there is no overall increase in the number of pigs being used for human purposes."

>>8127548
Goddamed hippies ruining good science because the media told them to care about this case. I work regularly with hybrid human mouse cells called 1A3. To me this is no different. We have been using animals to test on for centuries and this is pretty tame compared to the shit the pharmaceutical industry puts monkeys through. medical progress requires living subjects and i rather it be an animal than a human
