I told them it was a difficult question to answer and that they shouldn't be wholly basing their decisions on what they see today. Job markets shift and so will their interests as they go into university. Be flexible and build up skills and they'll find something which works well for them. As an example I told them I studied biology and chemistry before moving into CS, and then after being a developer for years I went into teaching.
