Being nimble is preferred. In the long run you can vertically and horizontally intergrate every available business and infrasture. It will save cost assuming those businesses are relevant. In the short-run you burnt out before those business "expired" or fall out of trend. The trick here is to have the right integration at the moment and expand in the market direction that favors it. Is like friendster and myspace too early to boom. Is like every other zoom-like businesses too late. The west has too high labor cost and seriously shortage of engineers. Countries in Asia like China, Taiwan, and SK churned out engineers like the women studies undergraduate in the west. The business environment in Asia will simply edge out the west. Remember solyndra? Remember GE? Remember Kodak? Upcoming is Tesla. There are so many Asian side EV coming in now.
