    I was posting on facebook, with some well known/famous people in scifi as well as interested parties, family and friends of those people..got into a discussion of old fashioned vs new, which turned into physical vs ebook, and physical people vs AI/mind uploading...to which one person in particular seemed determined to be negative...everything new was bad...I made a move to personal messages so as to not disrupt the original poster's thread and at first he was open, I tried giving him at least possibilities as to why the Earth was not doomed, how we might progress and salvage some of or worst mistakes...he started off by insisting no one had every changed his mind on such things and gave me permission to post some links...which I described in detail and summarized as well as posted my opinion on them...apparently he couldnt take it ..:lol: There was a lot of DATA there...It amazes me when people are presented with opposing evidence to the current zeitgeist of future dystopia how they cling to their negativity...wouldnt you want to join in the hope and contribute...to actually do something? I understand the biological drives toward negativity and exposure to media memes that harm us in the information age...where we absorb the most brain stimulating and visceral items, but why is is so difficult for thinking people (and he was not a dummy) to process this?

    The thing is, the future dystopia is more or less already established as our ultimate fate. The heat death of the universe is coming for us, you can try uploading your brain to a computer but it won't help you. And it's not like we have a lot of options for going around it. There are only two that I can think of are on the top my head, and they are not that promising to begin with.

    1. Breaking the second law of thermodynamics (or even better, the first one). Breaking laws of physics has to be somewhere in someone's famous last words, I'm sure...
    2. The possibility that there's something akin to quantum immortality acting as natural selection's cousin on civilisations at the universal scale. I admin there is some comfort that our civilisation could be playing the role of the Schrödinger's cat, but I'm still doing all the arrangements for my funeral.

    My personal consolation about the future is that the passage of time could turn out to be little more than a human perception that doesn't matter so much in the grand scheme of things. This would make it less relevant if our civilisation exists now, in the past or in the future.

    As long as we achieve everything that we can, explore everything that we have the ability to explore, we should just be happy we had the opportunity to do it. I see no reason to complain, our present situation is amazing enough as it is, and it is only going to get better. Just not as much as we would like it, but come on, what we've been part of so far is just overwhelming and indescribable... Without imaginary breakthroughs in the future. Our potential demise won't negate what we have had the chance to experience.

    Does the future not include paragraphs or the use of full-stops?

    Not everyone bases their conclusions on what they "want" and "hope." Some folks are interested in what's actually happening.

    Much the way it amazes many Christians how nonbeleivers cling to their atheism.

    Are YOU doing something? I don't know much about your background, but I never got the impression you have an active career in an IT field.

    Because it comes to techno-utopian/singularity theory, there are basically two categories of responses:

    1) People who get dazzled right away by the hype
    2) People who respond with guarded skepticism and say "I'll believe it when I see it."

    The second response covers the majority of people.

    The first response covers people who DON'T actually think things through but are easily moved to positive feelings by the promise of better things ahead. Some of these people are quite old, and have had this experience many times; a few of them are also fairly jaded by that experience and swing in the opposite direction, responding instead with RABID skepticism in a desire to avoid the pain of disillusionment.

    The second category (most people) are cautious adapters: they don't believe the hype, but they ARE willing to celebrate actual achievements and work to further them when it seems possible to do so. The first category, by contrast, covers the "true believers" who believe that ANY hint of progress is worth celebrating and honestly don't understand the skepticism of the second category. Ironically, they find the rabid super-skeptics -- who fall into the same category -- a lot easier to relate to.

    The heat death of the Universe isn't that bad, you just run your computer simulation into which you've uploaded yourself slower and slower - in subjective time, there'd be no difference. Of course, if all the black holes evaporate, all the protons decay, and eventually there's only photons left, you're screwed. But you're also screwed if dark energy takes hold and the Big Rip tears everything to pieces.

    That has the same issue that the Zeno's paradox does – by using half the energy, you're getting half the simulated time, so even if you can extend the real running time of your simulation to infinity, the time of your experiences inside this infinite simulation would still be finite. Second law of thermodynamic gives you finite amount of energy to do useful work with, which gives you finite calculations and/or physical processes happening which gives you finite experiences.

    Which sounds eerie similar to my understanding of the reasoning against quantum immortality – even if there is a quantum branch that saves you at each moment of death, death is still a gradual process that takes your life away bit by bit giving you less time of consciousness, in which even an eternal life would feel finite to you. That's more comforting than anything – quantum immortality is the walking definition of hell.

    It seems we're screwed regardless of how inventive or lucky we get. Well, you could try splitting quarks and then splitting sub-quark particles to get out more calculations per useful energy...

    Heh - I hadn't thought of it in terms of Zeno's Paradox. As you say, a finite subjective time would pass in an infinite objective time. The point about quantum immortality is also interesting - being condemned to live subjectively forever might be hell as you say.

    Barrow and Tipler had a theory that you could potentially "live" for (well, calculate for) an infinite subjective time in a finite objective time if the Universe were to undergo a big crunch -- another vision of hell.

    It become asymptotically more difficult to extract useful (free) energy as any thermodynamic disequilibrium disappears, and it gets especially tricky after all the black holes have evaporated due to Hawking radiation (after about 10^100 years).

    My apologies, I was condensing down a potentially much longer rant/post and in a hurry. Normally I try to use paragraphs and periods for legibility, even though texting, BBS posting, Facebook, and Twitter have taken me somewhat out of that habit.

    Making heat flow from cold to hot is pretty simple on a scale large enough where you can moving something at a measurable fraction of the speed of light.

    Imagine a giant turbine where the blades move out of the way as fast as light advances down the throat, so photons moving through the turbine never collide with a wall. Then make the backsides of the turbine blades retroreflectors (or stepped flat mirrors like stair steps) so light coming from the other direction, trying to go backwards through the turbine, is reflected back to the source. Then you have a broad-spectrum one-way light path. If you put it between two objects, the infrared energy will always flow in the same direction, regardless of relative temperatures.

    Unfortunately the turbine needs to have a huge radius or such a turbine would fly apart, since the blades do need to move at a small measurable fraction of the speed of light.

    But there you go. I've come up with a way to save the entire universe, and am just awaiting my royalty checks from advanced alien civilizations.

    When conditions exist that enable positivity in direct response for the predilection in human society towards negativity I feel it important to point them out. I feel there is equal potential for positivity (not utopia) as there is for dystopia...only the human mind feels the need for negativity. For most of the many horrible things that happen through human history you can find other equal, positive things (examples might include war, disease, poverty, etc..I can easily counter dystopians like Orson Scott Card on such issues)

    Again, we live in a time where the climate of change has enabled us to be able to more easily predict and model the near future, you cannot simply be concerned with the present, because what we're doing effects the future and far more quickly than ever. Identifying problems and fixing them, or creating a way to bypass them is a direct result of being aware of the future. Being aware of technological change creates a "self fulfilling prophecy" of sorts, directing efforts to where they are needed. I have given many examples of this in the last few years on this board.

    Several thoughts on this: I have maintained since my teen age years that the ultimate goal of current humanity might be to survive the destruction of our sun. You may project further, then the goal might be to survive galaxy collision with Andromeda. Projecting even further...and although I do have some issues with the potential science, you might also say that human survival ultimately will mean we need to survive the end of the universe..in this case, we would need to find ways into other universes or time-space.

    A good example of such staggering ideas can be found in Baxter's The Time Ships, where the goal of advanced AI/humanity is to survive into the multiverse.

    http://en.wikipedia.org/wiki/The_Time_Ships

    This is all interesting of course, but I'm really more concerned about the next 50 years right now.

    Nonsense, it is usually the negative response that is the knee-jerk panic attack. It takes greater care and wisdom to think things through, see what we've done right and where the areas are we can improve and fix, and where the technologies lie that realistically can do these things. Other efforts are political or social, and although these rise also with evolution, it is the technological arena that moves most quickly and is therefore most important.

    Yes, though I have no educational background with IT/software/etc, I'm using some of my background and interests to further some things in some small way that I feel will eventually lead to some of the things I believe will make a difference. In particular, I've been working with virtual environments, using my art background, though I have not devoted full time to this.

    Also, I'm involved with 3-4 organizations that are involved with both political and also popularization of futurism and accelerated change meme. I've contributed money, and also helped try and get a Singulatarian onto the US ballot. Only one country in the world has a publically announced Singulatarian in it's gov't.

    If I was younger I'd probably seek to go to the Singularity University, which I think is the most important one in the world for leaders, economists, technologists.

    Skepticism is great, I have belonged to and paid dues to skeptical organizations, unfortunately the people who say we can't do things in the future are the ones who WON'T accomplish anything, and also are usually proven wrong in the process...as has been happening the last few decades with accelerated change.

    That one's easy. So long as we figure out how to deal with this basket-egg thing they keep talking about, an achievable aftermath will be:

    Thousands of human civilisations get toasted by cosmic rays.
    Millions of human civilisations get ejected into intergalactic space to a slow demise in agony.
    Millions of human civilisations have their planets snatched by Andromeda, and subsequently colonise it.
    Millions of human civilisations have interstellar wars because of the star shuffling caused by the collision.
    The remaining billions of human civilisations across the galaxy do not notice that a collision had happened, and do not give a damn about the rest.

    Bloody, but survivable.

    Now, if we don't figure the egg-basket thing out, the ruins of the one and only human civilisation will have no difficulty roaming intact for eternity away from any star or galaxy until proton decay or quantum tunnelling takes care of them. And we would have gone with significantly less suffering.

    This comment is very revealing. You do realize there will be no physical collision? It will actually be more of a merger and take place over thousands/millions of years. We'll hardly notice it.

    Not "usually." Guarded skepticism is the more common response, but is often mistaken as "knee jerk panic attack" by people who find it hard to imagine any reaction other than technophilic rapture.

    Mainly that's because the other side of the "knee jerk" coin is "Cool invention! What a great time to be alive!"

    Not EVERY technological breakthrough is indicative of the approaching singularity, or even indicative of any sort of revolution in AI/cybernetics technology. Most are actually quite mundane developments of existing technology, and a few are old classes of little-known technology that is finally reaching maturity.

    And that long and careful thought process is rarely exhibitted by proponents of singularity theory.

    In other words, drawing pictures and spreading the word. Because hyping future developments is the same thing as helping to bring them about.:vulcan:

    You COULD do that, but you'd probably be better off going to MIT or Cal Tech... you know, a REAL university that produces actual technologists (like, for example, Ray Kurzweill).

    Hell, if Singularity University is an option, you're better off going to Devry. At least there you can learn a programming language and actually develop working software apps instead of just spamming threads about how exciting computers are.

    Which is all well and good, but the people who hype singularity theory don't accomplish anything either. You may be excited about what you think could be happening in technology these days, but you're not PART of that process any more than we are.

    Actually I expected you to chime in on this;)...and yes it is true that the distances involved are so great that there will likely be few if any physical collisions involved...but our solar system is likely to be effected, in fact ejected to a different part of the galactic halo...and while this might leave us unscathed from interactions in other parts of the collision, I'm expecting or speculating that mankind will be not only on other planets but other parts of the galaxy by that time period(assuming it takes 500,000 years to settle the Milky Way with Von Neumann machines, we could have colonized the Galaxy 4 times over in 2 billion years), and the radiation from a newly created black hole as well as infalling gas from the merger may wreak havoc in other areas we inhabit.

    Now if you want to speculate even further into the future, cumulative effects of the merger will eventually destroy the solar system due to gravitic disruption of the neighboring stars..

    Gravitational effects of nearby stars are unlikely to be felt at all. The gravitational effects of the galaxy as a whole will be tremendous, but they would barely differ from one side of the solar system to the other. The solar system won't notice any of them as a result. Aside from ejecting the entire system, or grabbing it, Andromeda will hardly affect a single orbit in it.

    The legal and political ramifications of the collision with Andromeda will be tremendous. Once-stable star empires will find their territory being violated by other star empires' actual stars. How do the lawyers sort that out? Is the empire whose stars have the higher average velocity relative to the average of the two galaxies considered the interloper? Will we have to define inter-stellar "right of way" to resolve disputes? Will the interloping star systems have to pay damages for orbital disruptions? It will be chaos.
