This is what frightens me the most about (and for) the younger generations, and the future of the human race.
A little off topic, but it is pertinent to the subject. A few years ago, (more like 10, now that I think about it!) I started going to Chan Buddhist meditation classes at a local Temple. You could stay afterward, and they would teach us things, answer questions, etc about it.
An interesting concept is the age we live in now is the called the "Dharma Ending Age", and they believe that we are headed for a 10,000 year long "dark ages", because
true knowledge and wisdom will cease to exist in this plane, and ignorance and chaos will reign.
This more recent, sudden and very alarming directional shift in society in general, but specifically in younger people due to their technological dependence, for the reason mentioned by you in the quote above, is a real path by which, in one generation, a whole civilizations knowledge could be lost. If nobody will bother to actually learn it, and the information gets lost, it is gone...
My co worker and I were discussing this very topic today, and he emailed this link about the fragility of information in the modern age.
