"A better analogy for progress is a young lake, growing from the continual melting of a glacier. As water is added to the lake, progress happens along all edges of the lake, all at the same time, continuously, and gradually. With this viewpoint, new technology doesn’t develop linearly from the old, it grows outwards from the centre." https://sookocheff.com/post/opinion/progress-is-a-lake-not-a-line/
