There is an argument that our tools make us smarter. There is another argument that our tools make us more stupid.
According to Plato, Socrates believed that written language was harmful, since it could lead to relying on external memory aids, and therefore impede true understanding. If anything, humanity has gone deep into the waters that Socrates warned against.
Where things get complex is the way that we are intertwined with our tools. If you grow up with a particular technology, it can be argued that the technology becomes part of you.
If, throughout my life, I know that I can write things down, then the act of writing things down becomes a kind of extension of myself. The written words that I leave behind are arguably a part of me, and they help to define my identity.
One day in the future, when each of us is integrated with his or her personalized A.I., will we be smarter for it, or more stupid? We will certainly seem to be outwardly more capable, the real-life equivalent of Trinity knowing how to fly the helicopter in The Matrix.
But will that capability truly be part of who we are, or will we just be kidding ourselves? I wonder what Socrates would think.
