I would like to suggest that we are given a choice in the tech tree. The arrow flow path is already there, but we have to complete all the research in a vertical path (column), to unlock the next 'column'. In Foe there was some allowance to go 'ahead' with the path. You always had to eventually complete all the research, but it made it possible to plan a strategy that worked for you. Sometimes going ahead came back to bite you and other times it paid off.
