It's been a while since I've followed CHI, but didn't it used to be a slightly more technical conference? The second paper in particular ("It Didn’t Feel Right but I Needed a Job so Desperately’: Understanding People’s Emotions and Help Needs During Scams") seems like something that might be more appropriate for a sociology or applied psych journal.
Has it become more of a social-sciences adjacent tech research conference these days? (I'm not being critical, just curious.)
CHI has been a pretty big tent (and it's gotten to be a big conference) from the beginning and has always had a strong social/psych contingent. I believe the author is from such a background, so "papers I wish I wrote" is going to be skewed towards those kinds of contributions.
But there have been and still are plenty of what I would technical papers; just skimming the program there were sessions on pose/gesture tracking, haptics, VR, and of course zillions of AI things.
CHI has evolved a lot over time, due to changes in how people use computers. CHI is a large umbrella conference with many subfields (Design, Privacy and Security, Accessibility, Healthcare, Education, Visualization, Games, novel hardware, novel interaction techniques, and more.
Note that CHI still has some technical papers. There are also other specialized adjacent conferences that focus more on technical aspects of HCI, like UIST and IMWUT.
