You shall all burn beneath my light!!!
Sorcery is exceptionally powerful in the modern era; Death of Obsidian Butterflies can still wipe out a large portion of a fighting force, including damaging light vehicles or low flying aircraft like an VTOL's or attack choppers going low, Demon-Summoning is still one of the most powerful spells in the game, a gun isn't going to you much good against Blood-Ape who has a dodge Excellency and who does agg damage to mortals (though heavy ordnance does level the playing field, but that was true even in base Creation) furthermore, in the age of mass surveillance and wire-tapping, Infallible Messenger provides a means of communicaion that's largely immune to mundane surveillance.I know I wouldn't. The ability to toss off spells is amazing even compared to modern weapons. Travel options that people can't take away from you? Summoned beings bound to you? All stuff that, as is, is tremendously useful even in a modern game.
Not to mention that even in the modern era has famines and droughts, Summon the Harvest and Water from a Stone spells are still very powerfull and useful.
And that's just Terrestrial Sorcery, the higher levels are going to be just as powerful, if not more so, in a modern era. Teleportation is still absolutely fantastic, even in an era with modern transport, and Third Circle Demons are still city killers.
