A good design process starts with brainstorming unfettered by
practicality. The next step is to take those ideas and start applying
filters to the set of ideas you came up with in the first place, and to
turn a more pragmatic eye toward the realities of those ideas.

In a thread like this, I think that people chime in on different steps
of this process. With something like adaptive beamforming, which is
not a new idea, a lot of the practicalities have been hashed out and a
lot of people already know about them.

I think it's worth avoiding the interpretation of responses as
reflecting on one's abilities or character or intelligence. Richard is
good at pointing out in some detail why a very hard problem is very
hard.
