Perhaps Grok 3 has reached AGI; it’s able to recognize BS better than a majority of US voters. I would have loved to see Elon’s face when they realized Grok was “woke”, and they had to botch this prompt-hack to censor it.

I regularly use AI assistants like ChatGPT (instead of @devoxxgenie.bsky.social or @intellijidea.com assistant) and I've seen that it helps a lot with coding questions if you provide some initial project context/information.

As a kid, my parents were watching TV and on the news they reported that some group started using “guerrilla warfare” In school I was taught about Hannibal with his elephants, but using gorillas? That’s mental. My 10yo brain created scenes straight from the Planet of the Apes 🦍
