The confusion comes from the differences in what words like 'obvious', 'trivial' mean in Mathematics and what they mean in English. Same deal with the word 'significant' in Statistics and English.

I used to take swipes at Haskell and Category theory folks for their use of their ektomorphisms but later realized the point of using words that are not used in regular English.

In mathematics obvious/trivial means no new math or technique needs to be invented to go from this step to that step, it does not mean it would be easy. This is fairly standard usage.
