As a former medical and scientific illustrator, learning a software package (Photoshop or GIMP) really isn't as crucial as learning principles and practices of art, design, and graphics. Color theory, negative space, composition, etc., are critical to production and apply to any media one chooses to work in: oil on canvas, pen and ink, or computers.
The other issue is access. Again, from an art/graphics/design perspective, costs associated with proprietary software can limit some students from even participating in art/graphics/design programs. Adobe Creative Suite is US$69.99/mo or US$840/yr.
