Technology today largely taps into the same types of human intelligence that knowledge work tapped into when we worked with pen and paper. Read and think, put your ideas into words and 2D diagrams, dialogue with others. But human intelligence is broader than this.

• When we ride a bike, we understand how it works kinesthetically (understanding lives in performing of it), iconically (graphic understanding of how gear ratios work, wordless way of understanding), symbolically (language). need to show an example that is more clearly the realm of knowledge workers but still has non-language representations. Maybe understanding of something in astronomy? Or engineering. Bike could still work, but have to talk from engineering perspective.
• Bret Victor goes so far as to call this style of knowledge work "inhumane," in that it forces someone to live in a way that severely constrains them - our method of knowledge work limits how we think, and takes away from our full range of intellectual capabilities @Victor2014HumaneRepresentThought.
