You can ask for C, C++, PHP, Java horror stories. You can ask for AWS, GCP, Onprem, Digital Ocean horror stories too and get some. You can ask for developers, system admin, DBA horror stories, MySQL, Postgres or Oracle. Just because you get a story doesn't mean the topic in discussion shouldn't be used or isn't useful. Sometimes horror stories happen because of ignorance.
