Good teachers realise that the students are the antenna; they are sensing things that the teachers don't yet sense.

With devices my technique is always to hide the handbook in the drawer until I've played with it for a while.

It's normally those other things that interest me.

Something I’ve realized lately, to my shock, is that I am an optimist, in that I think humans are almost infinitely capable of self-change and self-modification, and that we really can build the future that we want if we’re smart about it.

Also something that you don't have to listen to from beginning to end - you can enter at any point and leave at any point.

I love good, loud speakers.
