I hope we get to that "10x better" point. I think the problem right now is people advertising LLMs as if we're there already. And it's not just the providers, it's also the enthusiasts on X/Reddit/etc that think they have found the perfect workflow or prompt.
Just like you're mentioning "maybe better prompt engineering", I feel like we're being conditioned to think "I'm just not using it right" where maybe the tool is just not that good yet.
Well "I'm just not using it right" is a perfectly reasonable thought for a new technology. Isn't this the default? When new powerful tools come along, they often fit awkwardly into existing processes.
