1. Is it really better than a spreadsheet and a bunch of local scripts? How do you know if you haven't seen the code?
2. Are you still maintaining skills needed to make spreadsheets and write shell one-liners, in case the LLM service ceases to exist, jacks up the prices, or deliberately degrades in quality?
3. If this software is disposable, how do you dispose of it in a way that nobody in the future will accidentally use it?
(don't answer if you dont want to, just food for thought)
