If 80 million sounds too less for this mission, let us assume it balloons to 500 million. Even then look at the benefits it would bring. Make talented engineers/scientists stay in India and not migrate to places where 'more interesting' stuff is done. Check. Inspire a whole generation of people to take up science and engineering and to dream of thinking big, and actually have the confidence of knowing their dreams can come true. Check. Assorted scientific/industrial/capacity creation benefits. Check. All this at the miserly sum of 0.025 percent of your GDP. I think it is a very wise investment.
