This article nails it. The claim 10x is in my opinion one of these tactics used by large corporations to force engineers into submission. The idea that you could be replaced with an AI is frightening enough to keep people in check, when negotiating your salary. AI is a wonderful tool that I use everyday, and I have been able to implement stuff that I would have considered too cumbersome to even start working on. But, it doesn't make you a 10x more efficient engineer. It gives you an edge when you start a new project, which is already a lot. But don't expect your whole project of 100,000 lines to be handled by the machine. It won't happen any time soon.
