I am not going to argue with you about specific technology or use cases. But these are complex pieces of software, and the fact that you consider them to be "boring technology" is the reason why I was talking about "extremely boring technology". When you are building software really fast, you need to take the boringness to the next level and cut all non-essential components. At fly.io, hosted Redis costs over $100/month, when one server + Postgres is less than $10/month. This tells you about the complexity. Many people use Redis with Django, because that is "obvious choice" for Celery. But either Django built-in tasking (or backport with django-tasks) allows you to handle most of the use cases (long-running tasks, timed events) when combined with a cron such as Superchronic. Many people consider ElasticSearch as an "obvious choice" to handle full-text search, but Postgres can handle it in most cases. Mostly, if you have problems that require "webscale solutions", then you will have a team building a dedicated solution anyway.

There are a couple of points I'd disagree here. 1. I don't believe tenfold difference in pricing PostgreSQL vs Redis at fly.io is due to complexity, Postgres is much more complex. If I had to guess at why they priced it that way, I'd say it's because they choose more RAM-beefy machines to host their Redis instances. Other providers may have the pricing completely different. 2. It's been a decade that Lucene-based search engines are no longer the default choice. If for some reason PostresQL's FTS is not the right choice, there are many excellent alternatives like Meilisearch or Typesense.

  1. fly.io sells redis hosted by upstash. But you are correct in the sense that default fly.io PostgreSQL was unmanaged and probably subsidized, and recent PostgreSQL is probably more expensive. But while I think you cannot directly say that tenfold increase in price means tenfold increase in complexity, I am just saying that it is complex. 2. It is surprisingly common to see people preferring Lucene-based search engines over Postgres. I don't know about your alternatives and not saying anything about them.
