I wonder in what areas of science are we living/will we be viewed by future humans in a similar light as we view adherents of the “4 Elements” theory big nature are viewed today.

Quantum theory is only around 100 years old. Maybe we’ve got everything right, but I suspect we’re not the first people to have that thought and therefore we’re probably due for significant learning about the universe in the next 100 years.
