I studied both Computer Science and Fine Arts and Design. I was always interested at the intersection of these two disciplines. At certain point I discovered the work of John Maeda (at MIT Media Lab at the time) and realized that what I want to do is to make images with code.
At the time there were very few people taking this type of approach to art/design making. Digital arts meant using Photoshop not writing scripts. Nowadays more and more creatives from various disciplines use code as a tool of creative expression. Processing.org (direct descendant of Madea's ideas) is a huge community of artists who code.
What I find interesting is the cross over inspiration between the disciplines. Learning some new tech or algorithm feeds my ideas for visual works. And studying (traditional) artworks pushes me to develop programs to create similar visuals. One side very often inspires the other.
Often working on multidisciplinary teams (on multimedia type projects) I feel like people who have exclusively one type of background are somewhat handicapped. Artists who fear code are dependent on geeks to implement their ideas. And coders have to hire designers to create interfaces to their inventions. A lot gets lost in the translation!
Individuals that have knowledge and skills on both side of art/tech equation seem tremendously more innovative and can move forward much faster with their ideas. Ability to create complete functional prototypes or demos that work and look/feel good without having to ask/pay other people is freedom! I wish education systems recognized this and brought technology to art schools (beyond mousing in Photoshop) and arts and design into engineering schools.
In practical terms I use my dual skills working as UI/UX and data visualization designer/developer and I have an art practice creating dynamic images with code. Recently I won commissions for digital fine art frame company to create series of generative art projects. (I was told I was the first artist who codes they work with...).
In summary, amazing creative thinking and innovation happens at the intersection of fields and it might be difficult to quantify, but individuals that step outside of their main area of expertise always benefit in my opinion.
