We do. Here is a cut-down version of it being expressed and built: https://www.youtube.com/watch?v=U6jtCVOQiuA (Note: it uses our old interface, so it is a little rough.)
Is that video really supposed to show the power of this thing?
That visual template you saw was actual contracts to agents in the network. As soon as the expression is built, these agents receive contracts and the hive compiler begins forming. Bytes return shortly thereafter.
This technology does still have a long way to go, but it has the potential to do some powerful things. Right now though, we (the Code Valley team and developers who have joined and are joining) are still in the phase of populating the lower layers of the network. We are working our way up... when the behaviour layer (the 'top' layer) is populated with agents, the 'power' you are looking for will be more clear.
