We need more consideration of upsides and perhaps less trying to convince skeptics, because I think practice is going to win out over theoretical arguments against AI.
This post tries to explain why I find language models exciting. But it doesn't try to persuade skeptics that they should agree. It's aimed more at people already working with AI, and its goal is to sharpen our collective sense of what the upside potential might be. #MLSky 🤖 🧪
