Folks are very critical. Consider: this is the worst they will ever be. You improve one robot at one task, they all can share that training. It will only get better from here.

People being super negative about this is a bit surprising to me.
I guess it's kind of natural because when you agree with stuff there's not much value saying "yes this is right" but if you disagree then you generally have a lot to say about why.
But also I think there are a lot of curmudgeons here. Back in my day we didn't need no stinkin robots and AI and toktik. And anyway I could make a way better robot, this is no big deal.
I remain excited about AI and my master's thesis on fine-tuning transformers with LoRA. However, Hacker News has encouraged me to dive deeper and recognize that current architectures may not be sufficient. Additionally, Richard Sutton was a revelation for me in understanding how gradient descent truly works.
