There were points in this article that made me feel like Rob Schneider in Demolition Man saying "He doesn't know about the three sea shells!" but there were a couple points made that were valid.

the nil issue. An interface, when assigned a struct, is no longer nil even if that struct is nil - probably a mistake. Valid point.

append in a func. Definitely one of the biggest issues is that slices are by ref. They did this to save memory and speed but the append issue becomes a monster unless abstracted. Valid point.

err in scope for the whole func. You defined it, of course it is. Better to reuse a generic var than constantly instantiate another. The lack of try catch forces you to think. Not a valid point.

defer. What is the difference between a scope block and a function block? I'll wait.
