I do not misunderstand why Nvidia has a monopoly. You jumped drastically beyond anything I was discussing and incorrectly assumed ignorance on my part. I never said why I thought they had one. I never brought up matters of performance or software or moats at all. I matter of fact stated they had a monopoly, you assumed the rest.
It's impossible to assail their monopoly without utilizing far lower prices, coming up under their extreme margin products. It's how it is almost always done competitively in tech (see: ARM, or Office (dramatically undercut Lotus with a cheaper inferior product), or Linux, or Huawei, or Chromebooks, or Internet Explorer, or just about anything).
Note: I never said lower prices is all you'd need. Who would think that? The implication is that I'm ignorant of the entire history of tech, it's a poor approach to discussion with another person on HN frankly.
