Millions across the world, especially in developing countries, drop out of school because they (and/or their guardians)
see no benefit from long-term investment in education. Others who somehow manage to stay in formal institutions are exposed to decontextualized education that they cannot realize their full potential.
There will be many different solutions to it. One of them could be a large-scale, technology-immersed learning system that teaches a broad range of topics to students through a vocation. The vocation could be decided based on the learner's interest and the local resources. For example, in northern Nepal, child walk through perilous snow-covered hills and mountains to recover Yarsagumba ("Himalayan viagra"), a fungus with aphrodisiac and medicinal value. Instead, the kids can be educated progressively in details about different aspects surrounding Yarsagumba - mountain climbing, biological systems, business, marketing (where they could sell the collected Yarsagumba), greenhouse and high-tech farming systems, technology, etc. - without disturbing their Yarsamgumba collecting activity.
This is a simple example. Since a diverse topics are being taught and practiced, learners would not be restricted in the same vocation.
