Obviously you should not use a technology without understanding it. Does this really require a discussion? No one is on the other side. But going "Well that technology is just hype" isn't understanding it, it's dismissing it.

Let's not pretend like there's a single technology out there that isn't constantly under fire.
If you strip out the strawman argument against each technology ("Let me tell you a story about how this technology didn't work in my imagination") you end up with one single premise - do research before adopting tech. Did you need to be told that? I think if one single person is making tech stack decisions in production and no one is going "uh can you justify this" you have far more serious issues.
