Has the cost of building software dropped 90%?

I tried leaning in. I really tried. I'm not a web developer or game developer (more robotics, embedded systems). I tried vibe coding web apps and games. They were pretty boring. I got frustrated that I couldn't change little things. I remember getting frustrated that my game character kept getting stuck on imaginary walls and kept asking Cursor to fix it and it just made more and more of a mess. I remember making a simple front-end + backend with a database app to analyze thousands of pull request comments and it got massively slow and I didn't know why. Cursor wasn't very helpful in fixing it. I felt dumber after the whole process.

The next time I made a web app I just taught myself Flask and some basic JS and I found myself moving way more quickly. Not in the initial development, but later on when I had to tweak things.

The AI helped me a ton with looking things up: documentation, error messages, etc. It's essentially a supercharged Google search and Stack Overflow replacement, but I did not find it useful letting it take the wheel.

Like, is there truly an agentic way to go 10x or is there some catch? At this point while I'm not thrilled about the idea of just "vibe coding" all the time, I'm fine with facing reality.

But I keep having the same experience as you, or rather leaning more on that supercharged Google/SO replacement

or just a "can you quickly make this boring func here that does xyz" "also add this" or for bash scripts etc.

And that's only when I've done most of the plumbing myself.
