Yep; but its worse. A lack of knowledge doesn't just stop you from building some applications. If you don't know what you're doing, its really easy to accidentally end up with security vulnerabilities in the software you make. I don't want my data ending up in yet more have-I-been-pwned dumps because beginners don't learn the basics. Eg, lots of stack overflow answers recommend setting "Access-Control-Allow-Origin: *" to "fix" certain errors. Cross-origin messages are disabled by default in modern browsers for a good reason. No matter how convenient it is, you should understand the implications before opening flood gates like that.
