You are correct most people in software development have had an interest and experience for long before adulthood. However that prerequisite doesn't have to be that compulsory. We teach rocket science and brain surgery in universities, and don't expect the students to have experience in such before entering the course. Art, however, may be an exception (see below). I think it's about how Computer Science is taught. A subject can be taught effectively and learnt by enthusiastic learners. Anyone should be able to turn up to a university and get taught how to program, with no prior experience. What is essential is an enthusiasm and dedication to learn, and the skill of being able to learn to learn. Now - the above standing, Fine Art degrees and such often require the learner to do a Foundation Year. This year (from my limited understanding) is mainly a year of technical skills to bridge the gap between art at school and art at university level, and a year where the student tries all forms and mediums to choose the one they want to specialise in. If educators at university level see that there is a need for such basic education, perhaps a foundation level in basic computing could be an option.
