Fermi Paradox Solutions

Comment: I like 4G Ascension

It is said the ultimate possible computer might be a blackhole. The issues that exist with blackholes are blackhole evaporation, and whether blackhole computation can be meaningfully used without external systems interacting with it. Even if blackhole evaporation couldn't somehow be dealt with, a suitably large enough blackhole would last a very very long time so that might not be a significant issue. Whether a blackhole can be used in a computational sense without devices externally interacting with it is agood question. But if a civilization can effectively miniaturize computation to the max and actually live as simulated entities within a blackhole, this might be the ultimate level. Perhaps turning into a blackhole and sending it in motion towards the center of the galaxy increasing its mass and converging with other blackhole class civilzations.

UPDATE: 

 “Maybe in a highly advanced civilisation, physicists could create a black hole that didn’t evaporate,” he told New Scientist. “It would be exquisitely difficult, but mathematically you can do it.”-source new scientist

Ah, interesting. let's hope it is indeed possible.  If it is possible and if it is possible to ensure a blackhole performs the useful desired computations, then you've effectively found a way for immortality, true immortality.

Was disappointed with heat death and the showing that time crystals might be unviable, but this may potentially be a way towards man's dream, the final conquest of death

UPDATE 2:
The earth might or might not be hit by mini blackholes about every 1000 years, as they're one of the hypothetical possible dark matter candidates.    The idea of containing blackholes has been suggested, perhaps using opposite charge to contain black holes carrying charge.   Don't know how feasible it is, given that if these exist they'd be relatively fast, but there may be someway to slow and capture such black holes, speculatively speaking.

It is said that a micro blackhole would take countless billions of years to assimilate the earth, so even if containment of such was compromised it wouldn't apparently be a significant hazard.    The frequency of black hole collisions is in part informed by the idea of evaporation of even smaller black holes, but even though difficult, if  it is indeed true that black holes can be made eternal, perhaps the initial conditions might have allowed for a decent number to form naturally.  

Given smaller size they should be easier to contain, if they do exist, and easier to stop if it is at all possible, assuming eternal black holes can have or be given charge.

If,  and this is wild speculation, if the rate of micro black holes hitting the earth(as a result of potentially eternal micro holes occurring) was higher, say once per decade, year, day, etc.    If that was so and they could be captured they might prove useful.

Though some say eternal black hole papers tend to have errors, and be wrong.  So all this would depend on several things being just so(decent hit rate, eternal, stoppable, etc).

Comment on Tim Sweney quotes regarding future of graphics and singularity.

"You know, we’re getting to the point now where we can render photo-realistic static scenes without humans with static lighting. Today’s hardware can do that, so part of that problem is solved. Getting to the point of photo-realistic dynamic environments, especially with very advanced shading models like wet scenes, or reflective scenes, or anisotropic paint, though…maybe forty Teraflops is the level where we can achieve all of that."-second source link

  An interesting quote regarding future graphics, right now high end cards are around 10 Tflops, think even with manufacturing tech progression slowdown there might very well be about 30-50% performance increases per year.Even at a very conservative 30% increase per year in about five years we will reach around that figure.  Which will be in the very early 20s.

" To do completely photo-realistic rendering of everything, you have to simulate realistic humans and actually simulate human intelligence, emotion, and thinking. It’s not a matter of computing power. If you gave us an infinitely fast computer, we still don’t have the algorithm. We have no real clue how the brain works at the higher levels. You might understand how one neuron interacts with other adjoining neurons, but the large scale structure of it is still a complete mystery. That could be unpredictably far away. Once we are able to simulate human intelligence, what’s going to separate humans from people? You’re talking singularity level stuff at that point, but I do think that we’re many decades away from having that ability.."-second source link

I expected photorealistic graphics around 100Tflops, but as I'm not as knowledgeable it appears that around half the figure might be more accurate.    While some estimate human level intelligence requires several 10s of Petaflops, I think we need to take into account the sensory surface of the entity.   As animals increase in size brain increases in size to compensate for having to respond to a larger, more extensive, sensory surface, larger eyes, more skin, more volume of body, etc.   That is why there are animals with brains noticeably larger than human but which do not seem to display noticeably greater than human intelligence.

An entity with a simplified sensory surface need not as much neural hardware to perform well.   I've hypothesized that perhaps a highly simplified sensory surface might allow for a few 100Tflops perhaps as low as 100Tflops to perform well, perhaps close to human.   Of course there's a need for correspondingly large amounts of memory also to store the accumulation of dynamic knowledge or crystallized intelligence.

Comment on kurzweilai regards future bodies

The problem I see with singularity is near is that it assumes hard nano not only is feasible, but that it can work outside of specialized environments in manufacturing or research facilities.  

IMHO, it is likely that soft nano is the only nano that is viable in a wide number of real world environments.    Unless you design hard nano with a similar ease of dis-assembly and repair of components, it will have serious trouble dealing with failure of an internal component, let alone multiple components.   I find it highly unlikely that energy extraction, constant high speed motion, and bombardment with external agents*(high energy particles, especially in outer-space) can be withstood for long periods of time without failure of some internal component.    A biological cell can withstand countless multiple simultaneous failures of its internal components at the same time, how many can hard nanobot designs withstand before becoming nonfunctional?  in case of becoming nonfunctional how easy is the dis-assembly and repair?   The answers to these two questions will determine viability.

That said it is indeed likely that at least soft nano will be used to replace all of our internal organs with far superior versions.   Endogenous synthesis of all vitamins, and countless beneficial compounds will occur.   Long term storage of excess necessary trace elements to withstand possible suboptimal nutrition, and the ability to tolerate toxic amounts of these substances by storing some and mass disposing of unnecessary excess.  Also vast detoxification capabilities for poisons, the ability to withstand prolonged oxygen deprivation without damage, higher radiation tolerance, and cancer immunity with agelessness, and vast scar free regenerative potential.

IIRC, the idea of cartridges, belts or something like that was mentioned to deal with waste and provide raw materials and nutrients, this can possibly be accomplished with soft nano too.

Theoretically a linking system towards the blood supply could be designed, with a safe plug-n-play design, that would connect the body to an external machine that could provide nutrients and take waste materials and recycle them externally while using a computer or vr technology.

IF fusion reactors can be built and miniaturized or alternatively using wireless electricity, wastes would not need to go outside the body as there would be sufficient energy to internally recycle all internal waste produced and digest 100% all food, there would be enough energy to transform excesses into anything... say flowers?   Though with the advent of augmented reality food, excess consumption is unlikely.

Way I see it is likely that nutrient and waste exchange will occur while asleep, or if we do away with sleep while sitting or relaxing some, through a plug-n-play wire or if desired cartridge system, though plug-n-play wire seems less cumbersome.

Augmented reality food will dispense with most need for managing digestive waste, and aided by a system that harnesses either wireless electricity or nuclear fusion(less likely) it should be possible to handle real food without producing nonpleasant waste.   Wireless electricity would also allow for sufficient energy to recycle all internal wastes.
