> Nobody has a moat except nvidia

For now, for cloud training. but for consumers, nvidia vs amd reasonably close - the moat there is thin and shrinking. I suspect AMD will surprise us. nvidia has no motes in china, which may be a new source of (gpu) chip design. Huawei's Ascend 910C is about a generation behind... again: for now.

point is: moats dry up. I see nvidia's shrinking as a real possibility.

China will always be generations behind until they crack domestic EUV
