I have been through this before (wherever/whenever the money seems to flow) - databases are bad, you should use couchbase etc, I was a db expert, the people advocating weren't, but they were very loud. The many, many evangelistic web development alternatives that come and go, all very loud. Now the latest - LLM's, like couchbase et al they have their place but the evangelists are not having any of it.

I work a lot with doctors (writing software for them), I am very envious of their system of specialisation, eg this dude is such and such a specialist - he knows about it, listen to him. IT seems to be anyone who talks the loudest has a podium, separating the wheat from the chaff is difficult. One day we will have a system of qualifications I hope, but it seems a long way off.
