If we are getting so much productivity out of the current range of offerings from Silicon Valley, I have a question: why aren’t these products really expensive, as the technology of the 1920s clearly was? In fairness, a cell phone is costly – good monthly deals from major carriers usually make you pay about $600 for the phone. Which, funny enough, is what the typewriter cost (inflation adjusted) exactly 100 years ago. But what about all the free apps and services? Even Uber has to pay bonuses to recruit drivers. Why is that, if the model is so good? Yes, getting to scale is important for the service, but shouldn’t drivers come running if their productivity is so much better in the new model? Something is off.
