We did manufacture our own supercomputer when US denied us. - Not in large numbers due to budget restraints.
We also have space program- Problems with heavier payload but progress is going fine, had Moon Orbiter, conducted over 100 space missions, developing own navigation system, first it will be regional, builds own communication satellites with comparatively very less budget. Our moon mission was fraction of other moon orbiter mission. This tells our optimization.
Even modern nations had power black out. Only reason of 600 million people affected is because we have population of 1.2 billion, When US had blackout and its population lets assume for a moment, be 1.2 billion, we can imagine similar situation. We should talk about percentage wise, not number wise.
We produce excess grains but poor in management. Its due to corruption and bad distribution system.
We have highest number of railway passengers and hundreds of million of people travel through it DAILY. So providing basic necessities are necessary as the number of people traveling is way higher. We don't have HST because of money but we are planning to construct such corridor. We provide cheap travel through railways. The majority can't afford HST so there is no need and we have to transport higher in number along with in time consideration. Hope you can do the calculation.
We are building highest bridge in the world. We have constructed one of the best railway program by KonKan railways, find the pictures. Our dams are among the highest ones.
We are among the selective club of nations who has built SSBNs, firgates, corvettes like you and constructing 65,000 tonnage ACC with modular approach.
.......List is too long. We are behind because of our own reasons and poverty, mal-nourishment, diseases, education etc. which you guys always talk about. Now think, with all these problems, we have done fine, so how can we be low in IQ.
So buddy, just like you have English problems, we have our own problem, so instead of mocking each other we should rather discuss how to eradicate it or if we can't do that, lets remain indifferent about it.
