Yen Hung-sen makes an interesting point: "When technology has developed as far as it can, and the way ahead is a big blank, such that we don't know where further progress will lead us, it is perhaps time to start looking back for inspiration."
顏鴻森說的耐人尋味：「當科技發展走到盡頭，看到前面一片白茫茫，不知繼續下去可以走向何處的時候，不妨往回看，或許可以得到啟發。」
