Ben Horowitz on what it would take to actually see an AI "fast takeoff" scenario, using a framework from Databricks CEO @alighodsi : 1. Each new model needs far fewer GPUs than the last 2. Each new model takes less time to train 3. Each new model is more accurate than the last 4. It keeps happening, again and again "Zero of those four have been met... We're really talking about a risk that's entirely theoretical at this point." @bhorowitz on @theallinpod 🔗 View on Twitter
