In particular its opening paragraph (emphasis mine):

I tried out the Cline AI assistant yesterday, and then I went into a trance for five hours where I couldn’t do anything but stare transfixed at Cline fixing bugs for me.

And this part:

That’s when I was hooked

After Cline completed its initial implementation, I kept writing new testcases and then watching Cline update its code to satisfy my tests.

And that’s when I was hooked. I was so amazed that I could develop software this way. I just told the tool what I wanted, and it kept doing exactly what I asked.

I wonder how we can design video editing tool that can hook user to use it for hours? Going a bit broader, how do we design (traditionally) complex tools such that it's enjoyable and fun to use, like games.
