Very true. There's an enormous tacit knowledge gap. Check this out:

I have to use Mac for work. My WM is Yabai, which is controlled via Hammerspoon (great tool on its own), which means I can use Fennel, which means I can have a Lisp REPL. MCP connected to that REPL can query and inspect every single window I have on my screen. It can move them around, it can resize them, it can extract some properties of them. It's figuring out stuff like: "pick a selected Slack thread from the app and send it into an Emacs buffer", or "make my app windows work like Emacs buffers" - pick from the list and swap it in place. Or "find the HN thread about retiring from Emacs among my browser tabs and summarize the content"...

Never in my life have I been more grateful to my younger self for grokking the philosophy of Lisp. Recent months have only reinforced my firm belief that this 70-year-old tech is truly everlasting. Thank you, John McCarthy, for the great gift to humanity, even though so weirdly underappreciated.
