Say DeepSeek has worked out how to do more with less - that's great! I don't think it means that the market for Nvidia's silicon (or anyone else who can hop the CUDA moat) is going to shrink. I think that the techniques for doing more with less.. will be applied to _more_ hardware, to make even bigger things. AI is in its infancy, and frankly has a long way to go. An efficiency multiplier at this stage of growth isn't going to reduce the capital needed, it will just make it go further. There may be some concern about scaling the amount of training material, but I don't see that as the end of the road at all. After all, a human's mental growth is hardly limited by the amount of available reading material. After all written material is trained upon, the next frontier will just be in some other mimicry of biological metacognition.
At least that's my armchair analysis.
