People misunderstand ZT.  In the excitement of discovering a solution, 
what they fail to realise is that the conceptualisation of the problem 
was that which allowed for a solution to emerge.

It is for this reason that we introduced the phrase "squaring the triangle."

The point of ZT isn't that there is no solution at all, but that it is 
conjectured that there is no solution using one single technical component.

Therefore, you have to construct a solution out of components. 
Therefore you have to make compromises, design decisions, incur costs.

E.g., the wikipedia article argues that Szabo has proven it wrong.  Yet 
his solution proposes replicated databases, voting, vulnerability to 
conspiracy, etc.  A perfect example of compromise from composition of 
elements.

But yes, it seems that the current generation of bitcoiners have learnt 
that proclaiming success and moving on is a better strategy than proving it.

(Hmmm  Seems I've already written this in the Talk section.)
