Sitting in my garden this evening when an impressively-coloured bird landed three or four feet away. It just so happened that I had a portable device with me which could tell me, without me having to make any sudden movements or noises that would scare it away, that it was a goldfinch.
Now tell me. When, in the entire history of civilisation, has that been possible before now? Technology – it’s blimmin marvellous.
