That expression, "ideas are easy, implementations are hard", is lacking nuance. No, new ideas are ridiculously hard: can you have the idea for an alphabet if you have never seen one before?, even the banal equals sign is a ridiculously hard idea, Euclid and al-Khwarizmi never had such an idea [1]. Ideas are hard, implementations are sometimes hard, idea collages or idea twistings are almost always easy, given a ripening context: sliced bread; sell things, but on the internet.
