  This is partially true, in mathematical applications eg calculations, however humans excel at pattern recognition analysis eg recognizing images in photographs, interpreting emotions in faces (which current algorithms are not as good) and creative enterprise eg music, poetry. Artificial intelligence systems might close this gap in your lifetime.
