Pretty much every big tech company already has an office in India so why does this matter? The reality is the number of people in India who can compete for your job is limited and their standard of living and salary will keep getting higher. The other thing is that this is not a zero sum game. The demand for software developers isn't constant. It keeps growing and the availability of more developers will accelerate it's growth. Think of how much bad code is written right now that will need a complete rewrite in two years ;-) or x10 people to maintain.
