    1. I set ChatGPT up so every order has shipped email makes it go check if the price dropped since I bought it
    2. I have to chose between ChatGpt Pro, Claude, and IBM Bob. Which one should I chose?
    3. How are you structuring massive context prompts (codebases & multi-shot AI video) without burning 80% of tokens on noise? Built an open-source Rust tool (repOx) and looking for feedback

    1. Brian Chesky says AI doesn't equalize performance—it widens the gap between curious thinkers and average users because "everyone has the same tools, but it's no longer can you build it, it's what do you build"
    2. Unpopular opinion: 90% of popular prompt engineering frameworks (CO-STAR, RTF, Chain-of-Density) are completely overrated.
    3. Before I trust AI's "I checked it", I make it catch two errors I planted. That and three more rules replaced my complaints about AI lying

    1. Tired of Ai humanizer paywalls so I made one myself
    2. I'm building an open-source way to manage instructions across many voice agents. Looking for feedback.
    3. An agent typed the right reply, but the Respond button stayed disabled. Better prompting wouldn't fix it.
