Aside from what I mentioned, you're looking at Bruce Sterling, maybe a little Stross. I hesitate to recommend Doctorow -- he is faddishly distracted and senselessly optimistic. Vinge's "True Names" stands out. Maybe When H.A.R.L.I.E. Was One for the AI side of things. The amusing Headcrash, writings by Pat Cadigan, Jeter's deliciously dystopian Noir is a favorite if you want to see how bad it might get. Hardwired, by Walter Jon Williams, but that one has been a while.
