By that time world would have moved on from the 5th to 6th generation and beyond. Considering the march of the technology as its improving every 2 years plus there is already research going on into the 6th generation. We need to improve our economy, education, invest into R&D, infrastructure and export oriented industries so instead of setting goal for 2047 it should be middle or end of 2030's era. We don't need that lame excuse again that we couldn't shoot down 6 more Indian air force planes because our economy was weak and guess what Modi got more bold and went ahead and implemented article 370 and we sat on our backside and couldn't do a thing.
