re your last paragraph, I'm not sure (another commenter told me to be more positive so here we go!)
In my ~20 year career, a huge amount of tech has just been: servers, frontend, backend, databases, queues, caches, auth etc. The big shifts have been gradual and evolutionary (eg NoSQL, OAuth, React, SaaS, Cloud)
Big fads that were going to disrupt tech work as we know it have not entirely lived up to their hype (at least from my perspective): No Code, Blockchain, Serverless, GraphQL, Big Data.
Tech is a lot of big companies who move very slow. Particularly outside of SV/US where there is less VC hype.
But, it could be different this time. It's of course something to keep an eye on, particular if I feel I need to ride the hype train to get back into things
