What about wrapping nil in a Maybe or Option type?

This is good advice for humans: they can quantify to decide "too many nil checks" or not. But it's not good for agentic coding, which we're entering the age of. Although agents are the worst they'll ever be right now, they're never going to be great at quantifying too many nil checks. I think we'll have to get used to far more nil checks than even bad programmers put in. But that doesn't matter to agents, they've got infinite attention spans, no cognitive bias and large working memories. Sonn we'll see no nil checks.

Delegate all `nil` and bad input checks to a validation framework and use it in all your constructor functions.

Also known as contract programming vs. defensive programming. This argument is very old, is not specific to golang, and I have found myself on both sides at different points in my carreer.

This is the mess a language lands on when it conflates optionality (a semantic concept) with references/pointers (purely a machine concept). In Go, the requirement "need (non-optional) a reference to an object" is simply not expressible. This is a solved problem in other languages, for example `&T` vs. `Option<&T>` in Rust.
