The only reason why humans seem to prefer infix notation, is because it is what's being taught in school. The first mathematical expressions most people get to see is
1 + 1
There is no reason why someone who was introduced to
+ 1 1
at an early age would find it less "natural" than infix. I think the only reason why infix is the dominant notation is historical: Prefix notation relies on getting whitespace right as a deliminator, and that is a lot tougher to do in handwriting. Infix solved this problem by (ab)using the operator as a deliminator.
That is not necessarily true. the first tells me we are starting with 1 apple and adding another one. the second tells me that we are starting with Adding? Adding what? We never start with an action without having a object/subject in mind.
You are still starting from your own learned context. Other languages than English have different word order conventions. As a simple extreme example, in classical Latin the main verb generally is placed last in the sentence.
