Because I tell AI exactly what and very often how to write the code to avoid sub-optimal solutions AI so keen to propose if not properly directed.

As for autocompletion, not sure about every tool but CLion and other IDEs I have from JetBrains are genius. Yes they can autocomplete multiple lines of code with a single keystrokes and no I do not really want to write it myself as it mostly boilerplate code I've written many times and autocompletion just predicts it.

How can you recognize optimal / suboptimal solutions if you need to use AI in the first place? As for boilerplate, I thought there were ways to automate this without AI, but I guess that makes sense to me. Not trying to sound accusatory, just jarred by the AI hype generally
