I’ve just heard Dave Clarke, the infamous techno DJ, talking in a Resident Advisor podcast pointing out how strange it was that CDs came out in the early 80s containing nearly a Gigabyte of data, when the rest of the commercial technology market had devices of more like 32k – that’s 20,000 times less data. This geeky detail, when you shine a metaphorical torch on it, seems bizarre, and almost epoch shifting. Did the CD do more for the adoption of digital technology into day to day life than, say, the early desktop computers? And why is a techno DJ pointing this out to me, rather than a computer scientist or technology commentator?
