Good to see this out. The French Touch and Michael Bishop are exciting. The Warpath and Humanis chapters are also great, but my versions would have been written very differently. I particularly like 0rkCE0's thread in the HP chapter.
Did it appear earlier (I know it didn't make it into the cyber book), or is this book the first time that it's been revealed how Roxy is still alive and back on Earth with a new body? I cannot overemphasize how significant this is because, IMO, he's always been hugely constrained by other factors before now. 2083 Roxy has the potential to be a (literally) walking Dunkelzahn's-will-level plot device.
Convergence was my pitch, but obviously not my contribution. The only thing I will say is that, in Shadowrun, those with power use magic, the Deep Resonance, the Dissonance, cybernetics (in the most abstract definition of Cyber) to predict and shape the future. The single greatest obstacle has always been a combination of bandwidth and bias - there's too much information, and too many known and unknown biases shaping how information is produced and consumed. Convergence may have found a way around or through that obstacle, or at the least, found a better solution than anyone else has yet to achieve. At the same time, everyone else Shadowrunners worry about or should worry about is still grinding on as-is and is looking for better fixes with the goal of figuring out what the optimally predictable future will be and controlling that as much as possible. Convergence is basically Google in 1998. It's the best-working search engine in a sea of them. The difference is that IRL, Yahoo! and AltaVista wouldn't have murdered you for getting in their ways.
