I must confess I have a personal vendetta against Yudkowsky and his cult. I studied computer science in college. As an undergrad, I worked as an AI research assistant. I develop software for a living. This is my garden the LessWrong crowd is trampling.
I absolutely hate people throwing around the word ‘sentient’ like they know what it means. If you just read any dictionary it’s pretty obviously not some arbitrary word you can use to say it’s ok to kill animals.
