Over its more than 15 years in the wild, Google’s Go programming language has evolved from a curiosity for alpha geeks to the battle-tested programming language behind some of the world’s most important cloud-native software projects.

If you’ve ever wondered why Go is the language of choice for projects like Docker and Kubernetes, this article is for you. We’ll discuss Go’s defining characteristics and how it differs from other programming languages. You will also learn what kinds of projects Go is best suited for, including the state of Go development for AI-powered tools. We’ll conclude with an overview of Go’s feature set, some limitations of the language, and where it may be going from here.
