There were people who said the same thing about going to the Moon. Ultimately, solving the myriad problems implied by the goal of, "get some men to the moon and then get them back again (alive)," resulted in myriad new technologies and breakthroughs to solve those problems, which were not (and could not have been) foreseen. I suspect that getting to Mars and back (alive) will require solving just as many unanticipated problems and result in just as many new technologies and breakthroughs the ultimate benefits of which to mankind we cannot predict. I could be wrong, of course. It could all be the fantasy of some middle age men.
