Is this foresight a function of the CEO themselves or more of being in that position (ceo of a technology company). In other words, being in that role you have time and resources to think about "what is next?" also this is somewhat expected from the board and investors.

How much of their insight comes from others (eg. senior staff, acquisition targets, etc.) and how much from their own noggin so to speak?

Or a better way to ask this might be, how would one go about replicating this insight if one is not a CEO of a tech company? What resources would I need to pull in, who should I be talking with?
