LLMs are not going to replace a large number of people.

But they are very helpful, especially in coding. If you're not using LLMs in normal business development, you're going to fall behind.

It's made me a significantly faster developer, largely that a lot of the tedious work feels less tedious, and my projects are more polished.

You just can't vibe too much or you'll come out with an unmaintainable mess. There's a difference between using these tools responsibly and just producing slop.
