I'm trying to understand the relationship of humans and automation, historically and culturally.

I ask because the waterclock is generally considered the earliest form of automation, but snares and deadfall traps constitute simple switch mechanisms.

(They are single use without human-powered reset, but seem to qualify as machines. The bent sapling that powers the snare is referred to as the engine, which is "a machine with moving parts that converts power into motion.")

If snares and traps are a form of automation, automation has been with us longer, potentially, than civilization.

  • Are simple animal traps a form of automation or computation?

    $\begingroup$ Traps probably are simple single 'if-else' statement, whereas the other forms of automation probably require some more simple statements put together like maybe condition checking? $\endgroup$ – DuttaA Aug 9 at 4:22
  • $\begingroup$ @DuttaA think about what the inputs would be to trigger these machines, and what it would mean for the process to return "true" or "false". (I think there's a well founded answer here, but I'm interested to see if contributors have thoughts in support of or against this notion.) $\endgroup$ – DukeZhou Aug 9 at 16:34

  • Absolutely these traps and snares are a form of automation.

They take a task--harvesting small animals--which was traditionally done by hunting them, and make the process automatic. The mechanism requires a human to set up, but its function is automatic. This is to say that the mechanism operates without human involvement.

  • Absolutely this is a form of computation.

As DuttaA observed, these machines utilize a simple "IF/THEN" statement. In the case of the snare:

IF the hook is displaced from the base, THEN the sapling straightens

These simple machines will also return True or False:

TRUE: The trap catches an animal
FALSE: The trap is sprung but empty

The small animals are the input and, potentially, the output, depending on whether the mechanism returns "true".

(The use of "true" has historically included phrases such as "their aim was true" in the sense of shooting an arrow or throwing a spear.)

  • $\begingroup$ Comparing an animal snare with an if-then-statement doesn't make much sense. If/then statements were invented to control Turing like machines, while an animal trap was known before the advent of number crunching devices. A simple trap can full up the stomach but the rope can't be utilized for calculations. $\endgroup$ – Manuel Rodriguez Aug 12 at 18:46
  • $\begingroup$ @ManuelRodriguez That's entirely my point. Turing may have formalized how we regard computing, but clearly computational logic predates this formalization. $\endgroup$ – DukeZhou Aug 12 at 19:02

Automation?

Yes. When the mechanism keeping the trigger from inadvertently springing the trap after it is set is merely the static friction of a tangential force to the direction of the trap force, we have the below, where $F$ is force, $W$ is work, $x$ is the direction of the trap movement, $y$ is the direction of the trigger movement, and $k$ is the mechanical advantage gained.

$$ W_T = \int F_x \, dx \\ W_t = \int F_y \, dy \\ W_T = k \, W_t $$

It is not unusual for the friction of the trigger device to be deliberately reduced so that $k \ge 100$, meaning that the energy transferred from the animal to the trigger is no greater than 1% of the energy unleashed on it.

That the system has

  • A detection device (the contact point of the trigger),
  • A control function (the identity function),
  • Energy storage (the consequence of the setting action), and
  • A motor function (the trap release)

These qualify early traps not only as machines but as automatic one. The human that set the trap does not perform the identity function. The triggering design was performed in advance by humans, and even the purchaser of the trap need not understand it to set it and capture an animal. This clearly fits the formal definition of automation.

Computation?

No. The identity function does not require computation.

Deliberate Information Obscurity

This is not the only historical or cultural aspect to the information science involved. That the existence of the trigger and the action it triggers must be unknown to the animal is part of the information science involved. The secrecy is part of the mechanism, and the secrecy may not involve hiding the trigger or the spring mechanism from the animal. That the animal does not understand mechanical engineering may be ample secrecy for an animal that has not learned in DNA (by repeatedly eliminating lines of offspring that could not visually discern that something was amok) or

Does the System Learn?

No. It does not improve each time it is used. However, learning traps have been designed and are deployed today. The pray is the consumer in the case of marketing automation. The pray is the cyber-enemy in the case of national infrastructure defense or attacks upon it.

Is Any Learning Involved in Mechanical Traps?

Certainly. For the earliest traps to be fabricated, much had to be learned in advance by humans, again, either parametrically in DNA or in the human brain through experience or through language and education. These are just a few of many cognitive transitions that had to occur, represented as sentences.

  • Animals can be killed or maimed and then used as food.
  • Animals can sense human presence and flee.
  • Bending and releasing wood can propel somewhat like an arm can.
  • The releasing can be suspended
  • The animal can cause the release unintentionally

It is interesting to note that to artificially recreate the above learned understandings, both DNA and neurology were involved but not gradient descent, because the experiments and the analysis of results were discrete and no gradient could be calculated. It is also unlikely that it was entirely trial and error in searching for better ways to get fed. This is why logic based AI continues to be an important area of research.

Automation, which implies mechanical traps and tools like a hammer have made humans stronger. The automation device increases the productivity and is perceived as a pleasant invention. Nobody will reject a trap or a hammer as something not useful and insists on doing the same task manual.

In contrast, computational devices which are dominated by the invention of the microchip are working with a different understanding of reality. They aren't equal to improved tools which helps to increase the productivity, but they have flipped the relationship between human and machine. The human has to obey the computer and has to play the game, the machine likes. This is different from how past automation tools like a hammer is working. Automation devices have no need that the human has to obey to the device, he will always be in the social role of a master.

An automation tool like an animal snare fits well into existing role plays of humans. For example, a tribe is using the device for increasing it's food production. They can educate a person to become responsible for the mechanical device and the entire village will profit from it. In contrast, computational devices resist to become a tool. It's not possible to organize existing social structure around computers. For example, the programmer/hacker community is using computers to modify the society. They argue, that a human and the entire group has to follow the needs of a computational device..

  • $\begingroup$ Hammers can't be said to be a form of automation though--they are tools but not machines... $\endgroup$ – DukeZhou Aug 12 at 18:15
