I do think specifying JVM/PG/k8s in that comment was a mistake. Boring tech will be different for different people and companies. Boring tech doesn't just mean it's time-tested and battle-hardened, it means you have deep knowledge across the company because you've used it for so long. I'm in a Python shop, so Python is my boring default tech stack choice. If I introduced C++ into our tech stack, it would be not-boring tech for us, despite C++ not being a cutting edge language. k8s is funny to call "boring tech" because it's notoriously complex. But if your company has set up dozens of k8s clusters and has a bunch of k8s experts on staff, it can be considered "boring tech." It's all relative.
