Hmm .. I think I believe it's bumpy and lumpy, around and around, in & out, up & down .. but not truly flat. I'm probably wrong.

I think we will see the wholesale adoption of *temporary* hierarchies, depending upon what we want to get done and what's happening.

I don't think hierarchy as such is going anywhere soon. I wouldn't mind, tho' being wrong.

Hierarchy can be very useful at times.
