Go is definitely easier and more productive when you're operating in the happy path of web development with simple requirements and little tricky business logic. I wrote two extremely similar web services, one in Go and the other in Rust, and the productivity difference was night and day (granted, with some of that being experience). The problem is when you start to have to dealing with edge cases or want to express complex invariants statically. Fasterthanlime's articles, though IMO a bit excessively long-winded, are some of the best, most damning critique of Go's refusal to support correctness-by-design in a disappointing number of areas.
