A developer with four years of Go experience reflects on the paradox at the heart of the language: its surface simplicity conceals real complexity. Using a QR code generator as a case study, the post walks through four concrete traps: nil slice vs. nil map behavior, goroutine coordination pitfalls, the decade-long absence of generics and resulting interface{} abuse, and error handling verbosity leading to error fatigue. Despite these rough edges, the author argues Go's constraints enforce good design habits and that the language excels for network services, CLIs, and cloud infrastructure. The key takeaway is to distinguish 'simple to learn' from 'simple to use' and to understand Go's opinionated trade-offs before adopting it.
