Those are both mostly niche technologies, they're really nowhere near "the lingua franca of the Internet". In fact, "serverless" may well be past its peak, with many having tried it in AWS or Azure a few years ago, and then moving on to Kubernetes to avoid the extreme vendor lock-in. And while there are "serverless" frameworks for K8S, they are not as popular as more traditional deployments.
