Technological development (or lack thereof) in 2500 Turns

I find it rather doubting that a human society would develop so little over the turns of so many centuries. I mean all the Pernese are human beings like on Earth and look what has been accomplished here over the last 2500 years. Interesting, huh?

I think the threadfalls would have halted their development and the dragon's presence reduced the need for other technology

Susi, 9/7/98

it seems that Thread would more likely have stimulated the human inventive genius. And why  would the presence of dragons reduce the need for technology? First, they were available for a small minority (as far as transportation and other conveniences are concerned) and second, no matter how essential they were for fighting Thread, they were of little or no use in every day matters such as sewing, cultivating the fields or building to name a few.

Again, my guess is the survival thing - the battle against thread prevented holders and crafters making much progress.  There were also plagues that killed off the people with knowledge before they could pass it on to others.

As I understood it, the people who emmigrated to Pern did so to escape all the technology and political crap (such as war) that comes with it. When they moved to the Northern Continent, they probably left behind their technology on purpose. Also, such things as sleds ran on fuel, and it was noted that they didn't have a replacement fuel for when they ran out. I do remember reading about how someone invented a telephone-like thing in Dragon Flight/Quest or TWD, so there was some advancement later on. I just get the impression that they didn't really need technology, and as they say, nessecity is the mother of invention. They seemed to have all they need! : )

You also have to remember that the Pernese suffered from several plagues.  I remember at least one reference(in AtWoP) that Perns population was nearly decimated by plague... Remember.  It was Plague that brought on the Dark Ages in Europe.  Some anthroplogist speculate that advances in science & technology were delayed by as much as 300 yrs by the plague.  Pern was hit by several plagues.

Susi, 9/7/98

Hm, decimated or extinct? Sure, plagues would delay development for quite some time but not that long. Also I can't remember *several* plagues and I don't know of what kind they were (sorry, I still haven't read Moreta so I may be missing something on that issue. But hopefully it will arrive soon). Was it *the* Plague or just another epidemic? Well, 300 years are an amount of time a lot less than the time frame of the novels.

Moreta's plague was a decimation (1-in-10 killed).  You can't lose 10% of your population in a matter of weeks and not be severely impacted. Particularly when much information was communicated word-of-mouth.
There are two population-wide plagues directly referenced in the books: The first takes place in Fort Hold about 8 years into the 1st Pass (See _Chronicles of pern_), the second is the one toward the end of the 6th pass discussed in _Dragonsinger_, _Moreta_, and _Nerilka_.
There are also hints about several others dispersed throughout Pernese history.
Does the exact pathogen really matter?  Widespread disease kills lots of people.   At times, entire small communities.
The first plague at Fort hold knocked them back considerably further than 300 years of development.  And all you need is one epidemic on the proper scale every 300 years to ensure essentially zero development.

It's my understanding that Pern was a metal poor planet.  Without metal and with a metal-based knowledge, it would be difficult to advance.  It, at least, would surely slow advancement down quite a bit. 

Sariel, 9/7/98

The original colonists wanted to use as little tech as possible, so the culture started without an innovative drive.  By the second pass, society really started working on a "need-to-know" basis, which limited people to their specific sphere of life.  People not involved in a particular craft would not know where to begin asking questions, and within the craft the Master is pretty much the only one directing development--and we know they often took their secrets to their deathbed.  The basic cultural attitude of guarding knowledge instead of passing and extending it would keep technological development quite slow.  And the occassional epidemic, like the influenza of Moreta's time, certainly doesn't help either. By the ninth pass, even before AIVAS, this was changing.  Around the 12th turn of the pass, Robinton suggested starting classes to facilitate the exchange of ideas between crafts, attended by the youth from hold, hall, and weyr.  And Fandarel was quite innovative as Mastersmith, making intercoms and telegraphs, among other things.
