I'm working on what may be the last 2D project i'll do for a long time. It's for a book cover. After I finish this project i'm going to go full time back into Zbrush. My belief is that this(3D) is the next step of art and communication.
The tools are, in my opinion crude. Anytime an artist has to fumble or spend large amounts of time to use a tool there is a break down somewhere in the process. Zbrush is great for what it does, but it does have flaws when it comes to learning and just jumping in and creating.
I can remember when softimage was competing heavily with what was then alias wavefront. They both use similar slogans of "with complexity comes great power." Now that I look back on this, I can only say...what bullshit that was. There were times when I wanted to do what should be a simple task, yet it required advanced knowledge of scripting or the use "half assed" addon packages.
It seems that most software developers have learned from that and now keep the complexity beneath the surface where it can be utilized if needed, while the other commonly used tools and utilities stay visible and are easy to manipulate without too much complexity.
Anyone remember Kai Power Tools? When Kai Krause developed those tools he thought of how an artist would view the work space and how that work space would react to the artist. In some cases, he had versions of his software that would "open up" as you used it. Meaning that the more you used it the more advanced the options became to you. Simply removing the complexity until you were ready for it. Of course you could toggle this off and on. Le'ts not forget about Poser and Bryce.
The point being, more consideration should be put into the human interaction of software, or in this case, the artistic interaction of software.
If we do not kill off all of humanity in the next 40 years we will see advances in communication and art that we only thought possible in sci-fi books or films. Expect to see more holographic interaction where we usually see 2D such as Television, computing, and entertainment. This of course can not be done with out the creation or recording of three dimensional objects and space.
