Bots are better than humans at cracking ‘Are you a robot?’ Captcha tests, study finds
(www.independent.co.uk)
This is a most excellent place for technology news and articles.
I suppose it's this paper. Most prolific author seems to be Gene Tsudik, h-index of 103. Yeah that's not "someone". Also the paper is accepted for USENIX Security 2023, which is actually ongoing right now.
Also CS doesn't really do academia like other sciences, being somewhere on the intersection of maths, engineering, and tinkering. Shit's definitely not invalid just because it hasn't been submitted to a journal this could've been a blog post but there's academics involved so publish or perish applies.
Or, differently put: If you want to review it, bloody hell do it it's open access. A quick skim tells me "way more thorough than I care to read for the quite less than extraordinary claim".
