Do big companies need to die in order to free up their captured engineers, designers and dreamers?

That is, large companies tend to build a monopoly of talent. Which is a good thing for a while. Such an entity is stable and persistent, for a while, allowing engineers, scientists, designers and programmers to build their own stable lives and advance a solid base of understanding and financial consistency.

But in order for true innovation to occur, must these same massive corporations die in order to forcefully release their talent pool into the entrepreneurial pond — there to cross breed their ideas and create new collaborations?
