Having been through the system of IIT's i have to say there is lot of room for improvement in the existing IIT's. The government can spend more money to upgrade present IIT's and elevate them to the status of world class research institutions like IISc Bangalore, as of now they continue to be export factories to American University research. As such seats have been progressively increased in the last few years. I don't see any hurry to create more IIT's. The government is trying to cash in on the brand name IIT rather easily which is a bad idea as sooner than later, the fringe IIT's will take a toll of the reputation that the older ones created for themselves.They have decided to make the REC's, NIT's which is a good move as competition to enter them will be at a national level. Let them concentrate on creating a brand name rather than making some institutes parasites on the others. As far as the population growth is concerned well unfortunately our country as yet doesn't have the resources to match the growth in numbers. So i conclude we DON'T need MORE IIT's.
