“There a lot of ways to think about and approach technology. One way is to visualize stairs and each new technology is a step. Those steps climb upward to some unknown but presumed better end. Here’s an example: A step may be the most basic form of a wheel, then the next step would be something built on top of that wheel like a wagon, at some point you put that wagon with wheels on tracks and power it by a steam engine—another step, and so on until you arrive at today with a fully autonomous electric car with advanced sensors and artificial intelligence.”
