From the link: http://www.inc.com/best-industries-2012/darren-dahl/best-business-opportunities-2012.html

The team at Inc. has identified the industries with the best business opportunities for start-ups. Here are 11 industries that the smartest entrepreneurs should target for 2013:

1. Big Data
2. e-Commerce
3. Environmental Consulting
4. Full-service Restaurants
5. Internet Publishing & Broadcasting
6. IT Consulting
7. Mobile & Social Gaming
8. Pet Care
9. Residential Construction
10. Supply Chain Management
11. Water Conservation

If you notice, Technology has a MAJOR role in almost ALL of the above. I have repeated the sectors above with label of Technology, as below:

1. Technology
2. Technology
3. - some
4. - some
5. Technology
6. Technology
7. Technology
8. - some
9. - some
10. Technology 
11. - some 

So, 6 / 11 have technology focus, among recommended sectors / fields. Why would a smart entrepreneur be in a field that has nothing to do with technology and scale?
