I think we are confused when we say there should be more IIT's. Its because we think in terms of reputation as well as better education. IIT's do have name all over the world that's because of its better education. If we increase the IIT's it wont bring the reputation down if we make sure that all the parameters which make IIT's are there in newly found IIT's. If there are more IIT's there is definitely improvement in technical education that's what we want as a country and reputation of present IIT wont go down because then each IIT will be recognised differently like each REC is identified. Hence there should not be any Identity Crisis and give opportunity for present non IITs to go for higher education. In the end I would say talking of Exclusiveness is selfish but other would be good only if we make sure it indeed meet all present qualification of IITs.
