  In 1998, Fields medalist Stephen Smale [S. Smale, Mathematical problems for
the next century, The mathematical Intelligencer, 20(2) (1998), 7-15] proposed
his famous eighteen problems to the mathematicians of this century. The
statement of his eighteenth problem is very simple but very important. He asked
"What are the limits of intelligence, both artificial and human?". In this
paper, we prove that human intelligence is limitless. Moreover, we provide
justifications to state that artificial intelligence has limitations. Thus,
human intelligence will always remain superior to artificial intelligence.
Moreover, we provide justifications to conclude the limitations of artificial
intelligence.
