What are the disadvantages of the Go language from personal experience?

From personal experience, the main downsides of Go:

• Limited support for generics: although generics have appeared in recent versions, their functionality is not yet as flexible as in other languages.
• Lack of exceptions and limited error handling: the need to explicitly check errors leads to repetitive code.
• Minimal standard library: sometimes third-party libraries are needed for basic tasks.
• Limited metaprogramming capabilities: absence of a full reflective API and macros.
• Sometimes overly simple syntax: can lead to less expressive code in complex scenarios.

Nevertheless, these disadvantages are offset by simplicity, performance, and ease of maintenance.
