Silly statement, since "sorting" is a subset of "inventory management". Getting items from point A to point B, without conflicting with point C.
What it's boiling down to is that you've lost all context of this conversation, where you objected to the description of tubes as a dumb network. It's a descriptive term, opposite of a smart network, not a judgmental one. It's also a testable claim, and not based in opinion. Redpower tubes quality as dumb.
Give me a link to these oh so clear constraints you are testing against please. I have never heard of this ever so clear distinction of criteria.
"sorting" is a subset of "inventory management".
Thanks for stating my point. It only does a subset of the broader class, you are trying to make it do more than it was designed for.
