Why Interdisciplinary Studies?

Hank Green breaks down the pros and cons of why Interdisciplinary Studies are a great choice for the growing fringe job market in a tech-heavy society.
As a huge fan of Leonardo DaVinci, the Italian polymath of the High Renaissance, who was active as a painter, draughtsman, engineer, scientist, theorist, sculptor, and architect. I wholly believe interdisciplinary education should be the standard globally, as humans are rarely ever singularly-faceted. 
Yet I understand that academia as a whole is not entirely suited to fit everyone's specific pursuits. 
It is important to note the 2016 statistic Hank points to in the video which states, 65% of children starting primary school will end up working in jobs that don't exist yet.
