[QUOTEWhat do you mean by business perspective?]
Well, I think for a technology to survive and importantly have advancements over it, it is imperative that there is a valid business-case for its adoption/uptake. Cynical as this may sound, sadly, we are living in business-centric funding atleast for the majority.
My spin is that aerospace & defense technologies, unlike in past, are increasingly being treated to business-decision making logic and perhaps even a short-term perspective.
So when we discuss state-of-art technologies or possibilities, it is imperative that we also have some discussion abt the biz since it would help delineate the tech-advancement roadmap.
