premature optimization is a root of all evil.

also when those morons decide to do ‘microservices’ but end up creating glorified SOA with one messy DB where half the tables are not even used by anything, updates in place are the standard and there is nothing like one team per service, but instead everyone is expected to navigate millions of lines of spaghetti code with poor documentation, barely any reuse and inconsistencies all across the board with this oh too-fucking-common entity service anti-pattern.

and so much fucking coupling that you better start deploying your dev cluster just right after waking up so it maybe is up and running by the time your daily is over.

Fun fact, I used to work at a company where a lot of projects use Elixir and a bulk share of my coworkers have been outspoken critics of microservices precisely because OTP manages to power fault tolerant and scalable systems but not by insane levels of complexity like kubernetes does but by CoC that rarely gets in your way.
