This people you mentioned have nothing to do with our future, why? Because the only man who will create our future is our own. No matter what this people created will be useless if laziness of people will prevail and would not do in order to improve their lives.
I agree with Ranly123, specifically the bold text part. IMO, the future that they (people on your list) have influenced to is our present time and not our future.
When I read the topic title, I thought I could see a list of young and presently active person/s which contribute on the development of new technologies.
