I agree with the author 100% (the TanTan anecdote is great, super clever work!), but.... sometimes you do need Redis, because Redis is the only production-ready "data structure server" I'm aware of
If you want to access a bloom filter, cuckoo filter, list, set, bitmap, etc... from multiple instances of the same service, Redis (slash valkey, memorydb, etc...) is really your only option
