Nonsense. Crops yield more when agricultural information is applied. Crops yield much, much more when genetics information is applied...
Travel times aren't reduced since several decades, and where they are indeed reduced, it's far away from what happened in the 19th and early 20th century.
Travel time is close to 200 ms as packets travel around the world from me to US. Thus, my travel time to US is close to the speed of light in many cases (not all, but many), that's a lot faster then what became available in early 20th century (and much, much more comfortable).
From a productivity point of view, the information revolution is a disappointment. Jobs get slashed, but there is no increase in the creation of actual wealth or value.
Uh-oh. There are about 3.6 million of programmers in US, almost all nonexistant 30 years ago. These jobs were certainly slashed during infromation revolution... ooops.
