And you completely ignored my point that BGS can change the necessity of invention as they please, and so speculating on the necessity of anything is an exercise in futility.
I'm not sure if you're aware, but there have been quite a few TES games before Skyrim, and they have contributed to something called lore. And this "lore" is quite extensive, believe it or not. This lore sort of prevents Bethesda from saying "Okay now the entire reason this race exists is to develop technology!" instead of what their goals were in the previous games. Lore is kind of important like that. Bethesda has changed lore in the past, namely, changing Cyrodiil from a jungle to what it was like in Oblivion, however we had never seen the entirety of Cyrodiil prior to that. We have, however, seen each race on Tamriel in multiple games, and their motivations discussed in-game as well as in multiple in-game books, and changing their goals to such a degree would be a tad harder to pull off.
Not only that, but there are several facts of Tamrielic life that are so far unexplained. How, exactly, does a nation with absolutely no apparent industrial food production feed the Imperial City (or any of Cyrodiil's major settlements for that matter). How do the farms that are there cope without any kind of irrigation? Is the survival of the people of Cyrodiil completely dependent on the weather each year? Sounds to me like they need some irrigation and windmills.
Technology is necessary in Tamriel just to explain what the people already have. Conjuration is not capable of conjuring food and water as far as I know, and the majority of people only hold a pathetic command over magic. Technology, however primitive, is the answer to these issues.
So what you're saying is that things like irrigation and windmills do exist, but we haven't seen them? So then putting them into a future game would not be advancing technology, because they've already existed, we just haven't seen them because Bethesda didn't bother with those little details. I have no clue how you think them showing us how they've been doing the things they've been doing all this time will advance technology if it's been there all along.
Yes, I admit that I am coming off as quite the lore elitist. I'm sorry if having some respect for the integrity of the lore that has been established up until now makes me an elitist, but if it does, it does. The world of Tamriel can change drastically without advancing widespread technology, as evidenced by the events that took place in the time between the Oblivion Crisis and the events of The Infernal City. Those changes were largely political in nature, but nevertheless the setting is quite different now than it was in Oblivion. I understand if you don't want the setting to stay stagnant, but guess what, it hasn't, and it didn't need technology to do so.
If you truly need to see technology in TES to enjoy it, if you truly can't enjoy the setting without wondering why technology isn't developing, please go play another series instead of trying to alter the setting most Elder Scrolls fans have come to love.
