This is the problem. If you couldn't have coded it slowly in the old world, you will have problems coding it in AI world.
However if you have a lot of coding experience, you can now compress the time it would have taken you be an enormous amount. My experience is that I can now make extensive changes with very little effort, and very few dead ends. I've been able to take on entire secondary projects where I was just replication existing knowledge with slightly different tools.
Just this week I had a litmus test. I had an existing database that I'm pushing huge amount of data to. I decided to try a different underlying database. This would have taken me a full week of looking at documentation and writing supporting scripts, now I've done it in the spare time I had in two days of my actual work.
And it's not like the AI just did it all unsupervised. It threatened to do down the wrong path a few times, but each time I spotted it and steered it the way I wanted. I also asked it a few questions about curiosities I discovered in the emitted code, and that led to fixes as well.
If I didn't know how to code before, I would still be coding this alternative database.
