WAF has consistently held me down to earth. "What will that enable you to acheive that you can't do already?" With a couple mini pcs and a rpi I'm good. I'd love shiny things, but beyond LLMs there's not much it would enable me to achieve that I can't already.

That, and other hobbies. I don't want to be an amateur system admin during the summer. So all winter long, while I'm tinkering, I'm adding up how much it adds to my maintenance schedule.
