You really do have your head in the clouds. Or perhaps somewhere smaller and darker.
Do you seriously think that Kennedy said "we're going to put an man on the Moon" before asking his best technical people whether or not it would be possible if money were no object?
money is a symbol that is ever more losing its place in the world, information is turning out to be the new gold. The means to victory against enemies that can never be defeated, the designs of new engines of creation, that is the signal of victory in this day and age. Do you honestly think a country will be able to survive an assault against infinite armadas, rapidly cloned and taught armies, shields that can repel the atom, and weapons that self repair? The country that fails to acquire this, will be the country that falls first. The constructive power of the cell exceeds the destructive power of the atom, physicists may have stolen the fire, but it is we who are stealing that which grants power to the gods themselves, ambrosia.
The keys to building a society that can never be destroyed, a transition from the world of fragility and decay, to the world of the everliving.
What do you mean "you remember"? Were you there at those meetings? I think you mean you've read stories about people saying "it can't be done". Or maybe TV documentaries which like to blow these things out of proportion to enhance the human interest angle.
Well, guess what? Some very serious and prestigious people (for example Mr A Einstein) said it could be done. But they didn't say that because it was some whimsical meta-philosophical bullshit that they'd pulled out of their arse. They had very sound scientific reasons for believing it was possible.
Do you really believe that Kennedy and Roosevelt went ahead and spent billions of dollars on wacky and out-there programmes based on their own personal whimsical vision, and against the advice of some of all of the best scientists and engineers at the time? And that by oh some magic it turned out that the visionary Presidents were right, simply because They Believed?
Sorry but we've had numerous threads on this board along the lines of this one. Your arguments seem to be based on the notion that simply because some things which at one time were thought to be impossible by science have turned out to be possible, ergo anything which is currently thought to be impossible by science will eventually turn out to be possible.
Science fiction has a lot to answer for.
I'm a modern day polymath, and I can tell you nature's only shown the tip of the iceberg when it comes to cellular design. General ai is possible and it will be built, if we don't hurry it will be built by foreigners, while a collection of human may take centuries to master systems biology, a general ai given enough hardware and knowledge will master it in years if not months. Synthetic biology, weapons that cannot be destroyed even by a direct assault from the atom. Citizens that can be reborn even if indestructible shields, and working missile defenses should fail.
The world if it strays a bit from the one ideal path will not be a world lead by man and machine as one, but it will be lead by those most efficient and powerful, the machines as has been in the past shall be again, if we do not learn. Entire scientific communities replaced in a single stroke, the power over killing machines given to them by militaries all over the world eager for absolute victory, now the tools to master matter at a molecular scale are widely available in labs throughout the world. How long will a mind with no limits take to find unification and beat the entire community of physicists at their own game. Which human mathematician or group can compete against a collective that knows every single theorem and mathematical truth ever learned by man and begins working 24-7 on h/w superior to the brain from which to continue? NONE, even the entire community is a worthless joke before it, only with the aids of machines of ais do they stand even a remote chance.
BTW, my ideas an my algos, if any I have are those I'm stealing from the great programmer himself. It's been many years since I begun, and many years remain. But there are configurations of elements that given certain rules, can actually give birth to a mind, the brain is living proof of this, as much as you wish to deny it, this is what all the evidence suggests. A general ai born today is akin to an artificial god capable of granting absolute victory or defeat to any and all nations depending on who and why it is designed and how it is brought up and preserved.
