We took my three-year-old daughter Estelle for a picnic on Saturday. After driving around for a bit we ended up in a park on top of the greenest hill for miles.

It was a super pastoral scene: bumblebees, flowers and cricketers nearby, sheep grazing in the middle distance, the ghosts of clouds high above.

After we finish eating I say: ‘Hey Estelle, shall we go on an adventure?’

She replies: ‘Of course we can!’

‘What will we find?’, I ask.

She pauses for a beat, then: ‘A robot!”
