To me, it's always wild to see people trying to prove this is "the future" and "no one will ever code again". And then they try to prove it by building a react todo app, something that has been done millions of times and is really just an advanced hello world project...
I've had great success using AI for some tough things, but not on an entire foreign codebase that requires domain knowledge, no matter how constrained my prompts are. As soon as your use-case goes above the average "building a small tool and make it a $4.99 saas startup", AI really only helps you with the exact code to transfer your already pre-planned pseudo-code/behavior.
And even then, you need the knowledge to understand that what the AI merged out of the millions of StackOverflow answers is actually outdated or a hallucinated API function that never existed.
