Seems like another article based on the assumption that Nvidia just sits there doing nothing while everyone who has so far proven unable to compete suddenly figures it out and steals their lunch. At some point one of these Nvidia doomers will be right but there is a long line of them who failed miserably.
Fair Disclosure: I am very neutral when it comes to FLOPS/W/$ and the generality of those FLOPS. Given inference and training, the advantage is slipping.
