I really like your post and agree with most things. The one thing I am not fully sure about:

> Look at your app, describe a sequence of changes out loud, and watch them happen in front of you.

The problem a lot of times is that either you don't know what you want, or you can't communicate it (and usually you can't communicate it properly because you don't know exactly what you want). I think this is going to be the bottleneck very soon (for some people, it is already the bottleneck). I am curious what are your thoughts about this? Where do you see that going, and how do you think we can prepare for that and address that. Or do you not see that to be an issue?
