Indeed intuition is needed. When John Nash, a Mathematician with schizophrenia, was asked why he believed such irrational things when he such a brilliant man, he responded along the lines of "Those irrational ideas came to me the same exact way my rational, ground breaking ideas came to me." So intuition will always be needed, we just need to remember to check it.
