What was that old radio interview about personal computers?

Years ago, I saw on HN a fantastic link to an audio where a (British?) radio interviewer spoke to one of the pioneers of modern personal computing (Alan Kay?) and the guy keeps asking him what computers can do, that we don’t already have. He mentions human imagination, television, music playing and the Dewey Decimal system as things we already have. And the pioneer in computing is trying to explain how computers will eventually do programs to play music, or knit or whatever. And he explains how we will be able to find files, without the Deeey Decimal system. But the guy is skeptical.

If anyone here knows ... Can you please link me to such interviews, if there is more than one? Or to that specific interview? I would realky appreciate it! I can’t can’t it anywhere when I speak to people and make this point.
