Why not DualLink ?

[linas]

Reopening, because the questions were not answered. This is not a request-for-code-changes, or a suggestion that the unification code be discarded. Rather, its a request-for-post-mortem: what made DualLink unusable for chaining?

A subtext for this is "how do we design a general-purpose chainer?" because I still have the impression that the URE is not it (and yes, I have a glimmer of why DualLink is not it, either, but it is a glimmer, and not a full understanding). The meta-issue is that I've started writing yet-another-chainer, here: https://github.com/opencog/generate precisely because I don't believe that the URE can solve the problem that I actually have, and I don't believe that the URE can be fixed, either. Maybe I am wrong; maybe I can use the URE for this, maybe it can be fixed. Just right now, I just do not see how.

These are important theoretical questions. As long as we are all confused about them, forward progress is hard or impossible. This is a request-for-clarification. What went wrong, what is going wrong, why did the patient die on the table?

Unification is required because targets or sources can be patterns themselves not just grounded atoms.

I'm closing as I don't think DualLink can be used here, and we already have a unification tool for that.
