Good point! For my use case (on a different brand, Sony) I’m fine with the lowered resolution since I just use it for video conferencing, in which case the raw resolution is limited anyway. But for users who need higher resolution, using an HDMI capture card might be better for a one time fee rather than a subscription.

He’s apparently said he was born in 1988. In another thread others mentioned that would make him 21 when he started his PhD, which checks out.

You can do this on Linux using gphoto2, ffmpeg, and v4l2loopback. You probably won’t get full resolution but the quality will still be good enough for video conferencing. See here for a guide.

Not that unusual IMO, lots of people start their PhD directly after completing their Bachelor’s. If they weren’t born born in the first half of the year then they’ll have completed their BS by 21 and start the PhD either at 21 or 22.
