I see this false promise all the time: Simple tools are simple to use.

NO. Not necessarily. Use a handsaw to fell a forest if you like, or a hoe to till 1,000 acres. But I will not. Tool simplicity will come back to bite you if the task you're trying to accomplish is complex or high-scale. And simplicity of design in no way correlates to simplicity of outcome, or of your workflow using the tool.

Golang has, to be fair, more going for it than just its relative simplicity. But in many ways the OG criticism rings solidly true. The "we'll do just enough language features and tooling" becomes an abdication and an excuse in a complex world.
