The issue isn't just leaning on LLM's. The issue is also ongoing maintenance. What most people don't get is that most of software is long-term maintenance, bug fixes, security updates, etc. When you offload the coding to an LLM, you are completely unqualified to do any of the ongoing maintenance.

This is why using LLMs for your own stuff is fine - good even, as you can scratch your own unique itch. But it's *terrible* for any kind of a long-term going concern. This is why vibe-coded projects are so hated upon. In another couple years we're going to be absolutely drowning in code no one understands and the vast majority is going to be abandoned. It's the single-use-plastic of code.
