No need to bash on academics. For using and adopting blockchain technologies, self learning and passion are clearly more important than listening to lectures, but as the article notes, academia teaches the fundamentals necessary for foundations for building and making architectural decisions about blockchain tech.
Fundamentals like cryptography, finance, economics, and design are valuable skills that an academic education can help build.
The professors won't be making lectures on cutting edge blockchain tech because the new stuff is not settled. That's fine. They should keep teaching the fundamentals and equipping the next generation of developers and finance people with the tools they need to build and tweak new technologies. As blockchain matures, core concepts can stabilize and be taught as lectures.
she doesn´t exactly bash on academics, merely points out that the current education system leaves basically anyone in deep debt.
I'm glad you feel that way and hope that's all she meant, but the wording indicates that she believes the education system is better at generating debt than educating. That's effectively saying you're not getting your value's worth for tuition.
