No. He's right. Cruelty is corrosive to the cruel person. Courtesy and kindness help build up the kind and courteous person. Burning compute for courtesy is compute well spent.
Thats complete nonsense. Do you thank your terminal after it runs a command successfully?
I do. I also send my keyboard out for regular Shiatsu sessions and make sure only the most pleasant of colors grace the screen of my monitors. I'm still looking for the least irritating font (to my monitor, not to me). I'm also very polite to LLMs, I start every command with 'please', make sure it is framed as a polite request and I, of course, never ever get upset when for the umptieth time in a day it goes off on a 50K token wild goose chase driven by some hallucinated factoid that it really must get to the bottom off resulting in ever expanding circles of paranoia or batshit insane programming to bring about the condition it has convinced itself of must be the 'smoking gun'...
