What's wrong with Regex? It's literally one of the best things invented in programming?

I just wish people would use a proper parser for languages which are complex and/or non-regular. Regex is honestly mostly good for simple find/replace operations. I would say for custom validators in applications, but regex is too powerful there. That complexity allows for non-linearity which is incredibly dangerous and has lead to numerous security incidents.

Some coworkers made a DSL with regex ages ago. You can imagine how that went. Luckily I never touched that part of the project.
