Zoho's CEO feels that good software products can be developed not only in silicon valley or even big cities like Chennai and Bangalore, it can be developed in non-descript towns like Tenkasi too.

I think with more accessibility to digital media, and expansion of skills through internet education, skills can be diffused across geography, atleast in our field.
