Yeah use regex for its purpose (matching character patterns) and don’t use it for things it can’t do. That is just common sense and applies to any tool. But the argument about the email address validation confuses the tool with the problem to solve. The email address grammar is intrinsically complex, so if you want to validate an email address against this grammar (which I think is silly, but that is a seperate discussion) any validator implementation would necessarily be at least as complex as the grammar. Regex is not the problem here, rather it is the simplest possible solution for a complex problem.
