" In fact the most important step in spin recovery for the F18A was to disconnect the FBW computers and go to direct electrical link. "
Of course, the point was, that the pilots of most airliners are far enough from the center of gravity, where, in a spin, it is more like the infamous "G machine" centrifuge, astronauts trained in, than an F18A. The pilots of the larger airliner, can not take control because the G's keep their hands pinned. Although I think it's a good idea worth looking into, maybe an automation cure is worse than the disease. Instead of automation to get out of flat spin, maybe more training, to not get there in the first place, is a better use of resources. Maybe some resources to both. Doesn't always need to be either/or.
