1. Every major design corp has India campus, so India definitely has the talent for design
2. Coming to Fabs -- India lags big time. Why?
I am going to give a half-informed answers -- please fact check and correct me.
a. Dust -- at least the lower peninsula is Dusty (this has to do with Monsoons & Western ghats ..)
b. Water -- It is very hard to find the kind of intensive water facilities that do not go against agriculture sector
c. Silicon -- comes from Quartz and Indian Quartz comes from Andhra and Telangana is not of great quality
I can see India having fabs for domestic consumption and lower end.. not for export or bleeding edge.
note: Please down-vote if you think that is right and also provide feedback where I am wrong -- that would actually help here.
