RE:RE:RE:Nasa 1988 infoI can only assume maybe succumbed to the then power and dominance of Silicon and switched to the winner of the time. Others probably didn't have the funding to continue the R&D. Those who did, probably fell behind that of Taylor and patents, and realized their efforts were too far gone. I imagine some joined forces to work with Taylor. Others still may have continued, but just are too far behind. That and misc other outcomes.
