I am surprised that this article (which appears to be a marketing piece with superficial content) ranks so high on HN (#3 at the time of writing).

There are multiple inaccuracies. In particular, the article implies that tokens are universal to all AI—which is incorrect. For example, the statement that "AI systems depend on visual tokens to make sense of images" is wrong. This might be true of vision transformers, but not of CNNs.
