A global economic meltdown is pretty much inevitable. The shadowrun economy runs on capitalism gone mad. Capitalism depends on constant economic growth, which is utterly unsustainable in the long run.
Anywho, I actually managed to bring FastJack back in my fanon. The gist of it is that he got snapped up by Aztech, who then fried all of his nanites (and other 'ware) with EMP, using a Stabilize spell followed by a Heal spell to make sure it didn't kill him. After that his overwritten mind was more or less a blank slate that they pumped full of skillsofts for their purposes (which were horrible and psychopathic of course), after replacing the fried 'ware.
He did, however, remember one name: FastJack. He started to wonder who that was, or if it was him. He would periodically slip his proverbial leash to find everything he could on this "FastJack". Over the years, he started to put the pieces together, using it to build a personafix for himself. He's got a lot of "blank spots", things he can't remember because he couldn't find any info on them on the matrix. For starters, he no longer remembers his real name, and a lot of his old skills are gone, save for the ones his Azzie handlers plugged into him.
How he got out is a story all it's own.
