Some time ago, I found myself thinking about all our amazing technical advances - especially those that beg moral questions- and I began a journey that changed the way I approach technology, and changed how I think of humanity... and headphones.

"Should we be doing that?" I thought.

Should we be cloning humans? Developing implantable chips, artificial intelligence or nano-technology that may some day advance beyond our control? Will our technology unquestionably remain at our service? Will it's advance really improve our odds of survival, or will it just change it?

Is technology good?

Virtually every really bad doomsday movie launched from this string of questions. But even so, there are few certainties in life. Death being one. And, I need to add one other absolute certainty to that short-list:

- Man-made technology fails.

I have never used a technology that was perfect. It always breaks - it always reveals vulnerabilities - it always, always fails at some point.
