I think his obvious implication is that Go doesn't need map, filter and reduce because (if I may summarize) "line feed is just a single character".

That's just really poor (and silly) reasoning honestly. A 12-yr old could look deeper. For instance:

-. Is 'writing' code all that matters?

-. Aren't there in fact 10s or 100s or 1000s more readers to code than writers (including the original author also as a reader)?

-. Do readers like to scroll between various blocks of logic and divine signal from noise by teaching their brain to ignore boilerplate?

-. And what if the brain at first sees something as boilerplate but only upon further examination finds a subtle difference in the pattern for this one rare instance?

-. And what if that happens when the programmer is investigating a long-standing bug that has just resulted in a great loss of human life (and will continue to do so)?
