Per, Hank B's post - I think that the most amazing thing about this thread - is the apparent belief of many individuals that past generations were somehow not as smart or competent or talented as current or recent generations.
I find that attitude or belief to be extremely uninformed and arrogant. We - those of us living today - stand on the shoulders - of those past generations - nothing we have today would be possible without the intelligence, bravery, dedication, and sacrifice of those past generations.
I guess the uninformed belief in present day individuals as being smarter that past generations must come from the ability of individuals today to be more productive than their predecessors. Ie...a present day worker can produce more goods or product than his counterpart of past generations. Of course that modern workers productivity is dependent upon centuries of technological progress, vast databases of institutional knowledge, and a vast infrastructure.
The intelligence and capabilities of individuals have however changed little. Take a soldier of ancient Egypt, or Rome, or of the middle ages and let them spend a few months to a year catching up on technological advances and they would be as good as any modern soldier, perhaps better. Take a modern soldier and put him in ancient Egypt, Rome, the middle ages and give him a few months or a year to learn the realities and technology of the time and he would probably be quite inferior to the contemporary soldier of that time. Why, because modern technology is designed to allow average individuals to become quickly proficient whilst ancient technology often took more skill and training before one could become proficient with it.
Take a western pioneer and drop him in the modern world and with a modicum of training he could work for a living and get along quite well. Take a modern worker from the west and put him in the place of the pioneer and he would likely be dead in short order, because he would not have the skills necessary to survive and could not in all probability learn them quiclky enough.
In ancient warrior vs modern warrior as an example - the skill and training necessary to master the bow, sword, spear, sheild, and horse - the skills necessary to make and maintain the tools of ones trade, (sword, bow, arrows, spear, sheild, and horse, ect...) were more difficult to become basically competant with, than modern small arms.
Today we are more dependent on our technology and each other for our survivial than our ancestors.
