You have clearly misunderstood him. He does not claim that nature operates via pure randomness.
You are making the mistake of taking an either/or position ie you believe that either things are totally random, or no randomness can possibly be involved - hence your conclusion on page 1:
Right now, we're just simply showing the overwhelming and profoun sampling - but obviously we do not have the computing power nor time to solve it that way.
Clearly.
When someone says that it's all pure chance (the absence of any cause of events that can be predicted, understood, or controlled), I take that to mean that he considers that any order which exists is a result of non-purposive acts. Apparently, I'm not the only one who has misunderstood him.
Fritjof Capra:
"Jacques Monad saw evolution as a strict sequence of chance and necessity, the chance of random mutations and the necessity of survival."
Amy Bourne on Lewis Hyde:
"Hyde's insights into contemporary cultural change have been sharpened by a rich exploration into the field of evolution, as expressed by French biochemist Jacques Monad, Nobel laureate and author of Chance and Necessity. Hyde infers, "Theories of evolution have shown us that, even though it is difficult at first to imagine how a process that depends on chance can be creative, nonetheless it is by such a process that creation itself has come to be.""
Two more from Monad:
"Pure chance, absolutely free but blind chance, at the very root of the stupendous edifice of evolution: this central concept of modern biology [evolution] is no longer one among other possible or even conceivable hypotheses."
and
"The ancient covenant is in pieces: man at last knows that he is alone in the unfeeling immensity of the universe, out of which he has emerged by chance. Neither his destiny nor his duty has been written down."
Of course, he's not alone in the sentiment. From Gould:
"If the history of life teaches us any lesson, it is that human beings arose as a kind of glorious accident . . . surely the kind of glorious cosmic accident resulting from the catenation (linking) of thousands of improbable events."
Robert Jastrow:
"The scientific story of genesis has chance as its basic ingredient. You look at the story in detail, and every element of it is governed by some random event. A random collision among atoms that created stars including the sun. Random collisions of the molecules of life that created the first DNA, the first self-replicating molecule. This fact has both puzzled and distressed many students of the subject. They feel that since the story leads in an unbroken line from that chance event of a threshold straight up to man, there's something unsatisfactory about it, about a story that says man's existence on earth is a product of chance."
Clearly the above statement is false - yet as always you have not admitted your error.
I stand by the veracity of the statement. You've not shown where or how it is in error.
Why should he 'replace' the idea, when he never had the idea in the first place. No such idea has ever existed except as strawmen by the likes of you.
And, apparently, all of the folks cited above, including the source of the first citation.
It is not in need of replacement.
Which is it? It doesn't need replacement because it isn't in play (despite what these quotes declare otherwise) or doesn't need replacement because it's true?
Would you like to give a quote where he makes claims about the big bang and forces before those forces can be shown to exist?
Here's one very, very illuminating quote from the esteemed itinerant salesman:
"Darwin’s theory works for biology, but not for cosmology."
Personally, I like this one from him, but we'll leave it for later:
"A serious case could be made for a deistic God."
It is remarkably similar in nature to the OP where the random sequences were being compared for similarity to a target sequence.
Totally different. They have no idea what the answer will be, they are making predictions about unknowns based upon knowns without concern for either the number of attempts or time required to do so. The OP asks: starting at zero, how long would it take to get to the solution?
