So first, C++ in a small codebase with a small team, is a very powerful language that really does produce the best code. That's what you want in a professional, top tier code base and that's what you get.

Unfortunately, once a project grows to many developers, many of whom have varying levels of experience, it's just too easy to write bad C++ that becomes impossible to debug. I've been using it for a decade and I swear I barely scratch the surface of its features.

Lastly, and this one is the most annoying, C++ also has cryptic error messages that almost always never mean what they suggest. You'll learn to understand them over time and decode their meanings, but at first glance you'll spend long days hunting for the wrong issue.
