Honestly, I can't really argue with you on that. There's a lot of evidence to suggest that humans have actually declined over the centuries rather than advanced in terms of the sorts of things they can do under their own power-legendary heroes such as Gilgamesh and Alexander the Great couldn't be considered "weak and squishy" by any means, and if humanity was still in their league then we'd likely have very little difficulty conquering the known universe. As it is, the majority of humanity is in a completely deplorable state and relies on technology to compensate for their lack of any real ability. Even the most powerful mages of my generation pale in comparison to those who practiced magic even several centuries back.
