So silicon valley is bad _because_ they find more efficient ways to do things? Should we also be upset with anyone who sells a refrigerator, for making all those poor iceblock-expeditions and milkmen obsolete? Does the "\"sharing economy\"" (my quotes around their quotes, for how much they quote that term) mean that by using our cars, homes, tools, etc. more efficiently, and buying less new stuff, we're actually saying "drop dead" to the people who would have manufactured new things? Soon we and our economics will have to confront the massive efficiency boost of our machinery that gives us sufficient production of goods and services for less hours of work. We can let half the world starve, or we can educate and build for the future instead of the next big prophesied exit or fiscal quarter..
