I heard it expressed that AI is bringing a new era of small and personal software.
I think CMSes and websites are where that is most applicable. You no longer need these generalized abstractions and can now make your interfaces and data types just perfectly match your use case with little effort.
We went through great pains to build these mammoth, one-size fits all applications like Drupal and Wordpress for running dynamic sites across industries and companies with very little in common.
These days, I love to stay close to the model and stay close to the metal.
Glad to see we can keep the "every developer eventually builds a CMS" joke running for another two decades. I still think it's a bad idea to build your own, and I wouldn't put Drupal or Wordpress near the top of the pile for good ones anyway, but I'd still put them above any bespoke CMS I've ever seen.
