Not a panacea
Network access is not a panacea. Never has been, never will be. Yes, it can be good for some things. But it won't change the ox cart! If a third-world country's rural population is running at ox cart speed, no amount of network access is going to change that. The ox only moves just so fast.
The Internet made a difference in the first world countries because we already had networks, we were moving at the speed of trains, planes, and automobiles, and we had been doing so for quite some time.
