Indeed, a request for a short video call filters out most of the people who are looking to pad their resume with LLM-automated contributions, while adding an extra layer of welcome to genuine newbies who want to join the community.
I'm not sure if AI can do those today, but they probably can in the near future. (probably we will be able to see obvious "that can't be human" for a while longer)
It already can and it’s a big problem in recruitment. But for PRs I suspect it isn’t a big concern because this filter is to weed out PR spam from people who want to invest time in the project.
If you (or even your pet LLM) is able to set up v4l-loopback and some convincing realtime image/audio gen I think that's a signal that your PRs might be worth reading.
The point at which an AI can convince me in a video call revolving around a complex social interaction like an introduction and discussion of interests that it's human I'm gonna go ahead and let it have the title.
