So I wonder: is this specific to our culture or is a multi-cultural thing? If it is multi-cultural, then an explanation might be that hyper-focus on individual accomplishment was a more accurate perspective in our hunter-gatherer days; fewer people means that each person has a bigger relative impact.
I do have a specific opinion on what it means to learn form someone. People often overreach and obsess with details from the lives of those, when in reality learning from Einstein is as simple as reading what he wrote and the way he described his theories. This goes for many other geniuses -- they are geniuses in their fields, and we shouldn't expect everything they did to be right.
"If you want to find out anything from the theoretical physicist about the methods they use, I advise you to stick closely to one principle: don't listen to their words, fix your attention on their deeds."
"Oh, Einstein wasn't special, if he didn't get it, the next guy would have. Check out these folks instead." Somehow not sensing the irony that if we all did then worship the other ones you're talking about, you or someone like you would then just make the same claims on those people.. that they're not special, it was about timing and luck.
It's really not about the achievements for some people. (You.) It's just about having a person who only an elite recognizes. You're part of that elite and you're smarter for it because you see this other person's specialness and the rest of the world doesn't and you're better than them for it.
Einstein was great and original and irreplaceable. Your need to have found something better than what the common man worships doesn't make the other heroes you come up with worth any more, or Einstein any less. You just gotta get over it.
