Would you be willing to put a Future Technology Section in the Technology Section or Alternate History Section where we talk about Alternate Earths History?
You wouldn't be the first person to have asked of this, the reality is though that this site initially was (and to some still is) predominantly a science website. We have a Scifi subforum for "Fiction" and the Pseudoscience subforum used for "Pseudoscience and Fringe related discussion". If a thread or post is proven to have more prevalence to Technology etc, a moderator will move the thread once it's reached that juncture point to a different subforum. I hope this explanation is of use to you.
