Without a doubt, AGI will be invented much faster with a model to copy from. But similar to rockets, first we'll needed basic gunpowder, then refined fuels, all well before purified kerosene, well before liquified h2 and o2. LLM feel a lot closer to gun powder than even solid rocket fuel. (but because I'm exhausted by the hype, I'm gonna claim that is based on nothing but vibes)
