There have been plenty of articles about it recently, seems real enough to me.

I wonder if that's sustainable though, as either the tools get better or companies realise it's not a magic bullet? Time will tell.

It's not. The cost of fixing the garbage will outweigh any savings on the front end. Any experienced dev will tell you it's easier to spend a little extra up front to make things more maintainable then it is to fix a mess later.

And even the tools get better, they'll never get to the point where you don't need experts to utilize them, as long as LLMs are the foundation.
