You will be quite surprised how capable the system is, however I don't think anyone is realistically expecting it to be completely "done" at this point, it is simply a first iteration. On your other point that terms which are used are "programming stuff" that is certainly true due to nature of such systems, but the beauty of it is all that can be hidden from user as Rick showed. For example, at this point you simply don't care about how bend deformer in Cinema works internally, how it is coded and what is going on behind the scene and you shouldn't. It should simply work, be discoverable and easy to use, with simple set of controls for anyone to understand. Same principle is applied here. Advantage here is that in following period, more advanced users will be able to create pretty much anything that pops to mind and deliver it in any form they want. Also, as already mentioned, new managers that augment, complement, replace and work seamlessly with nodes will be delivered, so no, nodes are not enforced at all. Why not have best from both worlds? 🙂
