More on the 2020

Just back from Sydney, of which more in due course (once I plant a few trees to offset my carbon footprint, get some sleep and find my brain, which I know I left somewhere...) In between hopping on and off planes, I've been furiously journalising. To think that I thought I had given all that up! One bit of which, my report on the 2020 Summit, ran in the Culture section of yesterday's Guardian.
