That's quite interesting.

During the goldrush the most profitable and sustainable business were selling shovels, and that's exactly what nVidia are doing and are doing well.

CoreWeave and Magnetar are digging holes looking for gold - they may or may not find any gold, but they had to buy the shovels from nVidia to find out.
