Eno talks about failed experiments, the evolution of instruments and the notion that "technology is the name we give to things that don’t work yet".

I found the bit about piano v pianoforte quite interesting. I love Beethoven's 5th Piano Concerto (AKA "the Emperor"), but I've probably never heard it the way that Beethoven meant it to be heard - because he wrote it for a wood-framed piano rather than a metal-framed pianoforte. He can't have written it for or had it performed on a piano that could be heard against an orchestra. The development of the piano must have changed the way that piece is performed and our ideas of how it should sound.
