Not at all. This isn't a fact, this is only your opinion and these are not even comparable terms.

P.S. RPN corresponds to natural. It is exactly the way people usually calculate.

They refer to methods of calculating, so they are comparable in that regard. You are exactly right about RPN being “natural, and people will always slower and make more mistakes than a computer. That is 100% fact.
