Artists did not imagine vaccines or modern health care. (Neither did engineers, though.) Artists did not imagine engines nor engine propelled vehicles. Artists did not imagine communication networks before they were already in place. Artists did not imagine power relay (natural gas and later electricity and heat). We need people who understand how the world works and have intuition about what can be achieved and we need their minds roam free. There are very, very little novel things that aren't merely gadgets that were first imagined by artists and taken from there and implemented by engineers.
