Yes the article is very meandering. But near the end he mentions that the chips nvidia sold last three quarters alone would require about 15GW of electricity to actually run. But where are all the datacenters? And how long can this go on?

When the ground truth is someone keeps buying zillions worth of equipment from investors' money, but the chances to use it are slim, not to even mention getting some profit off it, there just has to be some fraud involved. Probably not on nvidia's side, but would not bet on it.
