A: They’re pretty darn good, but we don’t think they’re perfect. Perfection is a moving target. As soon as you’ve improved one thing, it’s impossible not to see something else that could be done better.
In the southwestern United States, there was once a tribe who believed that if they made a pot or a blanket without any slightest flaw that the gods would become angry and it would be big trouble. Well, in that sense of things I am pleased to report that we have so far avoided angering the gods!
We don’t think that the ‘perfect’ instrument has yet been built. To develop something that can never be improved seems impossible to the engineering mind.
