I think that if government starts building more IIt's then IIT loses it's place and would be just like a regional engineering college,just another engg.college in the corner,moreover i think that instead of building more IIT's govt. should give funds to upgrade already made IIT's to international standards ,because it's not the name only that matters but the engineers produced by IIT's matter.government will also not be able to find that class of faculty which is at present in IIT's .
