Most of the western country technologies were developed by joint collaboration and espionage....So don't feel bad if it took so long to reach here when nobody wanted to share technology with India...Developing technolgy that too under government that wanted to keep India poor and were funded by CIA is really great progress.. It is same party whose PM Indira Gandhi was afraid of her life when she wrote letter to Kissinger to spare her. She and Rajiv Gandhi despite being leader on Top couldn't trust the folks around them.
