"So string theory is certainly among the directions that deserve more investigation. But should it continue to be regarded as the dominant paradigm of theoretical physics ? Should most of the resources aimed at the solution of the key problems in theoretical physics continue to support research in string theory ? Should other approaches continue to be starved in favor of string theory ? Should only string theorists be eligible for the most prestigious jobs and research fellowships, as is now the case ? I think the answer to all these questions must be no. String theory has not been successful enough on any level to justify putting nearly all our eggs in its basket".
Lee Smolin, "The Trouble With Physics"
