It's been my personal experience.

Being able to use kubernetes for infrastructure, grafana, prometheus, etc Elasticsearch for search, Mongodb as database, redis as caching layer.

Knowing all these tech and being able to say you know these very well used to massage my developer ego...

Now I am much more like: Use one system to best of it's capability. Use Postgres. Mostly you won't need anything else.

I never resisted to urge to try out something new and shiny in production in earlier days.

Now I mostly use boring technologies and things I am comfortable with running in production.
