“Obviously, these dates should be taken with a grain of salt : predictions are wrong more often than not (check my 2020 tech predictions if you don’t believe me). They are often wrong because we tend to use history, which is at heart the study of surprises and changes, as a guide to the future. This should however not stop us from aiming to better understand the future of technology : the knowledge gained through planning is crucial to the selection of appropriate actions as future events unfold. We don’t know the answer, but we can at least ask useful questions and catalyse the conversation.”
