I don't know how to make sense of this level of investment. I feel that I lack the proper conceptual framework to make sense of the purchasing power of half a trillion USD in this context.
Can't answer that question, but, if the only thing to change in the next four years was that generation got cheaper and cheaper, we haven't even begun to understand the transformative power of what we have available today. I think we've felt like 5-10% of the effects that integrating today's technology can bring, especially if generation costs come down to maybe 1% of what they currently are, and latency of the big models becomes close to instantaneous.
