And the second thing is, is it's our job to try and find the right set of friends and the right job and the right role for that technology. And it may take many tries and constant interaction with that, and constant re-bending and tweaking and moving it around until we find a really good job for that idea. So we have an idea… it needs to… every idea needs to be placed in the ecology of other ideas and we have to find the right ecology. Because sometimes the idea in the wrong set will produce things that are not optimal for everybody.
So we are kind of parents of technology and we should think of them as our children. None of them will go extinct, they will never come back, we don't want to abandon them. We want to constantly engage them and train them for the future.
