A bit off topic but there is a very important point in your question to be understood. For myself - and the reasons which motivated me to accept Dynamo as an important industry tool - lies in sophisticated and recondite arguments about the nature of knowledge and complex systems. My position is probably better summarized in a blog post so please excuse the brevity and necessary abstraction of my answer.
Complex systems have many attributes, of importance to building design is 1) comprehension of the system and 2) the manipulation of said system. Graphical and computational approaches address each of these points individually. Basically, graphical representation tends to be much stronger at structuring complex data for human consumption. At the end of the day however, alpha-numeric input is much better suited for the manipulation of complex systems, especially as 1) the precision required increases and 2) the number of variables increase. There is no reason to believe a random post on the internet and I would encourage readers to look into software development project management where many of the behaviors described above are studied in detail and, indeed, leveraged daily to manage the software which runs the internet.
Returning to your question, the same analogy applies to REVIT and Dynamo. REVIT has become a powerful tool to graphically represent a complex system to a host of multi-disciplinary actors. But to efficiently manipulate such a complex system, which I do submit a modern building project is, a computational approach can be very valuable at certain points in a project. I harbor no ill will toward anyone wishing to model in REVIT but, for myself, I have every intention of building a lot in my life and to that end - I think it can be reasonably established - Dynamo has many advantages. As a side note, Dynamo is considered a visual programming language and I’m very grateful for this fact. Dynamo, for me, has reduced the intimidation of learning to program, as now I find it much easier to visually understand a complex program.
Computational Architecture = Rock n’ Roll.
