It’s been addressed a bit already, but yes, Mod S deffo agrees we need moar FUTURE in the au!
(Mod S would pitch in but she is pants at worldbuilding)
EDIT (Mod Z): There was an ask waaaay back that I previously touched on regarding this matter; in addition to magic sort of replacing technology in many areas, there are also numerous events that seem to happen every generation or two in which some sort of small to large scale catastrophe occurs. Considering the volatility of the energy that now resides in the physical world, disasters become more prominent… and humans hit anything from minor setbacks to “holy shit the power grids have failed in entire countries, we’ve regressed three hundred years”.
The biggest culprits would be the magic “storms” that pop up. These are unpredictable surges of energy that strengthen the link between the physical world and the dreamscape, and are generally disastrous because they affect so many things. The storms can brew natural disasters like atmospheric storms, earthquakes, tsunamis, tornadoes – anything. They can also give dangerous supernatural entities more power, make them crazy, or even birth entirely new creatures like dragons or spirits that have little to no self awareness and the overwhelming firepower. Perhaps the most dangerous side-effect that some storms bring are the random natural portals that allow powerful demons to enter the physical realm for a period of time without a summons or contract.
These storms can be mild, affect a single town and only make a few creatures go loopy for a few hours. But they can, and have been so enormous that they cover half the globe, and initiate a 2012 level of apocalyptic doom. The human race hasn’t been wiped out yet, but the existence of these storms have certainly kept them on their toes, and are the reason why they’ve failed to technologically advance at the rate we do in the real world right now.
(That’s not to say you can’t have a time where things are super sci-fi and advanced! This really is a forgiving plot aspect in which fans can take a lot of creative liberty and decide what kind of world humans live in at any given time.)
