Now consider this, can joy not be had in cooking? I can certainly tell you that I find cooking good food to be a very fulfilling task. Unlike engineering projects I can go from start to finish in under an hour. And it fulfills an immediate and visceral need.
I think that the argument for play is a good one. In engineering I encounter many people who engineer, not for the joy of it (which is spread very thin in many jobs anyway), but for the money. Now imagine if there was no quantitative social status (money) associated with engineering. You would see engineers self select purely on a basis of authentic interest rather than financial status seeking. Would that not bring more promising talent to the table?
Let me now attack the idea of automation from another angle; to claim that we should be able to automate all product is as outrageous as claiming that Atlas holds the earth up. How could we automate everything? Who makes the machine, and perhaps more importantly, who fixes them when they break. You cannot possibly convince me that you could make a machine to fix machines. Again, such a device would be in the realm of science fiction. In reality, even in the relatively controlled environments of factories things inevitably break in unpredictable ways, and there you are, back to needing humans to clean up the mess.
Now, automation does have a place; doing repetitive tasks. But I’d rather order a meal from an expert chef than a robot.
