We already have those near constantly. And we still keep asking queries.
People assume that LLMs need to be ready to replace a principle engineer or a doctor or lawyer with decades of experience.
This is already at the point where we can replace an intern or one of the less good junior engineers. Because anyone who has done code review or has had to do rounds with medical interns know… they are idiots who need people to check their work constantly. An LLM making up some functions because they saw it in stack overflow but never tested is not at all different than a hotshot intern who copied some code from stack overflow and never tested it.
