If you're just copying someone else's code, whether from StackOverflow or an LLM, you haven't made yourself a 10x developer. You may have found a shortcut through the boilerplate and repetitive code that occurs across many applications, but have you learned anything? Do you understand the code? Could you write it yourself? Using a forklift doesn't make me a 10x weight lifter. Finishing a paint-by-numbers canvas doesn't make me an artist.
Learning programming languages and writing the trivial bits doesn't describe the hard part of programming: domain knowledge and skillfully translating complex business requirements into working code.
