Southwind, the problem is that the trigger is still arbitary.
In the case of Sam the trigger is receipt of cash from the sale of his latest device. He has no intent. He's not sitting there thinking: "I hope my latest device is successful enough to sell so that I receive some cash that enables me then to go out and buy additional components that will enable me to make an identical device"
Sam explained that he’d simply connected wires to components and wires to batteries in a thoughtless fashion, and that he’d taken his ‘creations’ to school to try to sell them
Self-replicating systems self-replicate if the environment allows.
And Sam's electronics devices replicate if
their environment allows too. Put another way, if the environment
disallows then they don't get copied. It's the operation of the
environment to which Sam's devices are exposed that determines whether he receives cash (the trigger) that enables him then to replicate his devices, just like it's the operation of the
environment to which the cheetah is exposed that determines whether it reaches sexual maturity (the trigger) that then allows it to breed. The 'self' part is a complete red herring.
Mating is a means of self replicating, and not a "trigger".
So what, instead, can we consider the trigger to be then? Maybe 'trigger' is not the best word, maybe 'catalyst' or 'prompt' or 'enabler' might be better. But it doesn't really matter. What I'm identifying to you is that in both cases replication is not a given - something needs to occur to enable it. In the cheetah's case it's the attainment of sexual maturity; in Sam's case it's the proceeds of sales. Either way, that thing that needs to occur is a direct measure of the entity's ability to survive its environment and be 'selected' to replicate.
Should an organism not reproduce, because it dedn't mate, even if it had the chance to, then that particular "self-replicating" system wasn't.
I don't think we should confuse the discussion with irrelevancies, such as organisms that had the
chance to mate but somehow didn't. I think we need to pre-suppose for the purpose of the debate that the whole driver of evolution, whether natural or technological, is a 'desire', conscious or otherwise, to reproduce and develop. In any event, I don't see how an organism
not reproducing adds to your argument; it's just an aside.
The "trigger" for a self replicating system is at its inception.
By 'inception' I assume you mean 'birth', in the case of an organism. If so then you're using the word 'trigger' in a different sense from what I am. As amplified above, I'm using it to denote the point in time at which replication is
allowed to occur, i.e. the point in time when an entity has effectively proven itself capable of surviving its environment, which is a pre-requisite to evolution.
What happens when Sam gets the cash, he buys more stuff. This could be automated. The random alterations could also be automated. So could the selling.
If Sam has no cash he can't make copies, true. If Sam has cash he still has to decide to make copies.
In fact you can remove Sam completely from the story.
"I have two sons and an imperfect copier of electronic thingimys. "
The entire process could be automated, just making copies when cash is availiable.
We touched on this principle earlier in the discussion as furthering the strength of the OP analogy. If it could all be automated then, by definition, no human intelligence is present, but evolution continues. What are you now arguing jimbob?
But still someone would need to set that system going ...
Like 'something' needed to set the natural evolutionary system going too. I don't see how that concept serves to help invalidate the analogy. The catalyst for instigation, in both cases, has to be a given. The thrust of the OP is increased complexity over time, not how it all started.
... and set the parameters to choose what to copy ...
No. We've already established that Sam (or the automaton now, if you like)
does not choose what to copy. It only copies what it last made, just like in nature, and the trigger for the copying process is the proceeds from sales, which, by definition, form the proof for the device's success.
If the first variant didn't sell in one day, is it left until it does, or is it returned to make a new one?
Admittedly, there has to be a timeframe, but there does in nature too. The longer the cheetah goes without breeding after reaching sexual maturity the lower its chances of replication become, until it dies. The automaton in the analogy could be programmed either with an arbitrary timescale for sales or it could choose randomly, until a beneficial situation emerges, like in nature. Alternatively, it could monitor the environment somehow to see what else is selling instead, and elect to make the latest device 'extinct' based on some pre-set parameters, similar to nature. In any event, again, I don't see how the notion of a timescale, be it arbitrary or otherwise, serves to help the argument against the validity of the thrust of the analogy.
The analogy is getting further from both the OP, and from real technological development, and it still requires an intelligent agent to set the system up.
The reason it's got further from the OP is because it's an extraction of the original analogy, and the reason that it's been extracted is because it has had to be broken down further to try to get you and the likes of mijo and ID to see how it can work. If you were to accept these extractions, like the Sam & Ollie story, then I can show how they can be traced right back to the analogy in the OP, although that should be pretty apparent to you anyhow. All you need to do is recognize how intent and forethought (intelligence, if you like) are simply the inevitable extension of what Sam was doing, and that they've developed simply to short-circuit the otherwise convoluted process of technological development by chance. Sam & Ollie, as we have seen, would end up developing equally complex devices if time wasn't a factor. The same could have happened with the aeroplane or the computer or the motor car, but it didn't, and we can easily see why it didn't. That doesn't make the design development processes that we now see happening around us any more special than following Sam's approach, in the context of what emerges from it.
Any ‘bad’ changes were quickly eliminated through extinction, i.e. zero sales
Zero sales over what timescale and at what price? In the initial setup, "insufficiant sales" have to be defined. It might seem picky, but it is in the implimentation where the difference lies between self-replication and evolutionary algorithms requiring intelligent input.
I've addressed timescale above. As for price, each device simply needs to sell at a price that enables slightly better components to be purchased. This is exactly how it is for Mercedes Benz (except that they need sufficient funds for R&D too, which Sam didn't). But price is just one of many environmental factors that distinguish one device's characteristics from another. You could equally have questioned the device's ability to withstand heat, or moisture, or impact resistance. Price is just one of many factors that contributes to determining its probability of replication, just like claw length, lung capacity, eyesight, etc. are for the cheetah.
Price, like timescale, could initially be determined arbitrarily, indeed at random, through trial and error, until such time as the device succeeds, i.e. sells at a price that enables it to out-compete the competing devices, and such that additional, slightly more complex, components can be bought. This, to a degree, is what happens in the real world, and what happens in nature. How was the 'selling price' for primitive organisms determined in nature? By chance, that's how - no different from Sam's devices.
There are still copying instructions jimbob, even in Sam's little world. He might write them down or keep them in his head; that's not important. Sam doesn't have any instructions for making a coathanger or lump of mud, and his resources, i.e. his electronics components, don't allow him to make these alternatives, just like a cheetah cannot 'breed' a coathanger or lump of mud. Why are you suddenly introducing this concept, that something completely different could be made? We all know why that cannot and does not happen!
If something sells, how does the system know what has sold? I presume that they are identifiable, and then Sam decides to copy the variant that has sold as opposed to one that hasn't. He could decide to copy a previous "generation" if he wanted to. How does he choose? With an alogorithm?
The automaton (formerly Sam) only makes and sells one particular device (a 'species', if you like). The question as to what has sold, therefore, is not applicable. As explained previously, if a random variant is introduced which does not lead to decreased sales then that variant is retained. It has, by definition, proven itself to be not detrimental. If a particular variant leads to increased sales then that enables more and/or much better components to be bought, leading to an increased 'population' (in principle). Just like if the cheetah suddenly undergoes a beneficial macro mutation then it's population will also increase.
The automaton is not programmed to revert to previous generations; it just blindly goes on copying and randomly varying the current device. The only time it might be allowed to revert to a previous generation is if the device becomes extinct and it is decided not to start a new device from scratch, but to start with something that proved useful before (there's no saying that it will be a good starting point for what the market requires now, though!). In any event, what impact does the possibility of reversion to a previous generation have on the validity of the analogy?
Without self replication, something has to choose what is to be copied.
As explained above, only the latest device is copied. I thought that was clear from the Sam & Ollie story! This is, therefore, tantamount to self-replication.
I really don't see your point about sweatshops.
You claimed that Sam could choose to replicate his devices simply because he 'likes' them. I drew a comparison with a sweatshop to prove in a very simple way that things don't need to be 'liked' by the replicator to be copied. They can be copied just by following instructions, which is what Sam did. The scenario I set up in the Sam & Ollie story has absolutely no reference to 'liking' or otherwise. I'm actually very surprised that you missed the point of the sweatshop comparison. It really does make me wonder how your mind works, or doesn't, as the case may be!
Predation has nothing to do with this jimbob. I'm talking about the cheetah's ability to survive as compared to Sam's electronics devices' ability to 'survive'. What's 'selective' breeding and 'domestication' got to do with any of this? I've already clearly shown how Sam does not apply selective pressures in determining how to evolve his devices.
I assumed from this part below that you were arguing that the predators were concious agents of selection:
Well, when a cheetah is stalking a group of antelope patiently observing and waiting for some tell-tale sign of apparent weakness that inherently informs the cheetah that it might have just identified dinner, how, in principle, does that differ from a school boy at the bring-and-buy fare perusing all of the alternative novelties on offer just waiting for one to catch his eye because of something about it that informs him that he's likely to get the most enjoyment from it?
Rereading that, I can see you're saying that both are "selecting". I would argue that in the example of the market that the choice of varuiant is only the first part of the selection process. Somehow the information, that this variant is to be copied, has to make it back to the copier. With self-replication it doesn't. If it copies itself, it is an evolutionary success; if it doesn't, it is a failure.
The information, that the variant is to be copied, makes it back to the copier by way of cash proceeds. This is the 'trigger' that I've discussed above, that proves the device's 'success' in its environment. A similar 'trigger' is also required with self-replication. Whether a cheetah will self-replicate or not is not determined at birth. The cheetah doesn't inevitably self-replicate. It has to survive its environment long enough to reach sexual maturity then find or attract a mate. I think you're getting confused over the mistaken belief that self-replication is a given because no external agent is necessary. The
environment is the external agent that conspires against replication!
