Even if golang gets generics, it has so many other flaws that make it an non-starter for serious projects. This won't stop people who are driven by hype from using it of course.
Serious projects like major Cloud infrastructure? And what are these damning flaws? If they are damning performance flaws, then presumably no project can succeed in a language slower than Go. If they are static type safety flaws, then surely no project in a dynamic language can be successful. If they are lack of fine grained control over memory layout, then surely no major VM or interpreted language holds a candle.
