I can answer the question as of now, since I don't believe Vulkan is on at the moment. (Note: I will probably get some stuff wrong, so take it with a pinch of salt in case I am corrected)

For technology, the city is about the same as it is now. The tech is about as advanced as 2015, but new technology is being constantly discovered by the scouts. As for why, the 6 minute war all but destroyed it all. As for human genetic editing, I can say there is a bit of it, but that's kinda a secret following one of my character :p

As for powerful corporations. The largest by far is of course the New Order. For others, you can check the character tab for the Nexus and the Lost, as well as the other PC factions. Other than that, there is only one main civilisation which the the city we all live in, and probably the most influential group besides new order was the Cabal. 

Now, [@Vulkan], pick this clean until it's all correct :3
