alt Hacker NewsJev is only on people's mouths because they made friends with venture capitalists and used the publicity blowhorns that come with that.
Whereas the other guy went through the unglorious but formerly respectable path of publishing software and papers for other professionals to look at. A year ago.
We're in a bad place where the latter looks less reliable than the former.
(EDIT: I'm not saying the research here is in fact the same as what "Jev" is doing; and Jev is in fact more "product shaped." But I think it's important to temper the hype and back up and focus on the fact that this whole industry is built on research by both academics and enthusiasts ... first ... and gold rushes can often bulldoze over those people who are focused primarily on making-doing-researching instead of fundraising-hyping-promoting. That's not good.)
posting to arxiv is not publishing, it's a preprint site, and what's there I would not call professional work of academic quality
This was a year ago, when we were all complaining about the arxiv slop, which led to the new vouching system. This paper would not make it to arxiv today, it would be a zenodo link since they have not instituted any gatekeeping
