> New abstractions and techniques... hide complexity, and that complexity requires new ways to monitor and measure.

If the abstractions hide complexity so well you need an LLM to untangle them later, maybe you were already on the wrong track.

Hiding isn't abstracting, and if your system becomes observable only with AI help, maybe it's not well designed, just well obfuscated. I've written about this before here: https://www.bugsink.com/blog/you-dont-need-application-perfo...
