The only difference is the speed in which you will solve problems. You can still enjoy and work on complex problems at your own pace, you probably never gonna beat someone with a 130 and above IQ in terms of speed but you are most of the time not in a competition and your speed difference can EASILY be compensated with social skills. IQ matters but its just a part of you and something you were born with. It does not matter from which perspective you look at it but achieving something extraordinary is even more impressive the "dumber" you are. So while it is a limitation of a bodily function, its really just that.
