If you never used any particular tool, you probably wouldn't find it useful, right?
I asked Gemini about my unicycling this morning, and it coached me on weighting the seat; e.g., looking ahead instead of down helps unweight the pedals.
That's true. I've also never used a wheelchair, or a variety of other tools for people who can't walk, because I can walk without them. The same holds true for communication.
When I can get an LLM to write like Isaac Asimov, I'll consider some artificial literary experiments; there were books I wanted him to have written that he did not get around to, quitting at 458.
"Productivity" is not. It's only good for fake productivity. The consumers of the product will almost always be better off with you disclosing what the LLM did, and what you did.
I'm quick-witted, outspoken, playful, clever, apparently intelligent; Mensa, Colloquy, like that; not quite clever enough for the triple 9 societies. Morning pages readily enough dispel the illusion. Or coding. I scanned six years of morning pages into a PDF and fed it to Claude to distill for me; apparently, I have several thoughts per year. Damn, I'd hoped for more. Asking Claude Code to critique my code is, ah, good coaching. Ouch.
