Companies push the envelope via their product they are selling or marketing. If they are not selling consulting services then, in a vacuum, using e.g. nodejs instead of Java is not pushing the envelope in any meaningful way. If using nodejs actually lets you push the envelope in your actual product then yeah that's good. But in my experience companies are full of people thinking there are lots of silver bullets out there. The silver bullet is the new way to do it. The wrong way is the old way to do it. Related, lots of people jump straight from being 100% naive about performance and architecture to thinking FAANG is the only way to go. They don't stop to think that there are a multitude of midpoints between those two options. If your business model is to be Facebook or bust it might make sense. But I see a lot of pretty boring and simple businesses resorting to really over-architected solutions. Because the developers are so inexperienced that they think you need eventually consistent distributed microservice soup to serve 10,000 requests per hour.
