Good one, Alessandro! Thanks for sharing. In the last 50-100 years or so, we have experienced such about-face with the case of "misfits" or the "round pegs in square holes".
So, it´s interesting how today people that once were deemed as disabled can today be integrated into the society in general.
Nowadays, the blind can "see" (feel by touch) and read (braille texts), the one-legged ones (by accident, for instance) can now be understood merely as "disabled athletes", and can run with prostheses.
And many mentally impaired people underwent ECT while they couldn´t, or their conditions weren´t known yet (bipolar for example is a recently explained disorder, it wasn´t before).
That to mention just a few things and areas of expertise. There are hundreds of things of which we, and our predecessors were thinking that was wrong and not innovative.
"Think different" can bring lots of creations, inventions and new ways to solve old problems for us.
That doesn´t mean that everything our forefathers have done or thought is disposable, there are works that will help us today and perhaps forever (or for a long long time).
Thus, watching that last video, we could equate "think different" to "think flexibly", given some contexts it would be a more versatile way .
