He was the presenter of 'Tomorrow's World', the BBC show about innovations in science and technology which ran from 1965 to 2003. At it's peak in the 1970's, over 10 million viewers would watch Raymond Baxter perched on his studio bar stool as he demonstrated the latest gismo - some comical, like the fold-up car or robot seretary; some prescient, like the microchip or first home-computer.
It would be intriguing to imagine what the show would be like today. For a start, it would be difficult to explain to viewers how the latest gadgets work - how would you explain the iPhone, or even get the case open to show its inner secrets?
But what I really miss is the optimistic vision of the future behind every show - the feeling that we could shape our world and everything in it, make it better. The world is changing faster than ever before but we seem to be hurtling down a blind alley of apps and eco-sphere's which confine us, lock us in until we forget that we should be in control.
We need to look up from our tablets and smartphones and remember that the world is a real place with real, physical problems. And it needs us, human beings with imaginations, to fix it.
