Sure!
There are two broad groups we targeted. One was relevant classes; e.g. anything dealing with ethics, Peter Singer, etc. We would approach professors and ask permission to pitch our group to the class at a relevant point in the curriculum.
The other was other student groups. IIRC, we went to a local LW meetup (which only met once) and the Stanford Transhumanist Society, and had a joint Skype call to Rob Mather with Stanford’s chapter of Resource Generation. (There are likely others I’m forgetting about.) For the first two, we just showed up at meetings; for Resource Generation, it was a joint event arranged with their leadership.
[Likely not a crux]
EA often uses an Importance—Neglectedness—Tractability framework for cause prioritization. I would expect things producing progress to be somewhat less neglected than working on XR; it is still somewhat possible to capture some of the benefits.
We do indeed see vast amounts of time and money being spent on research and development, in comparison to the amount being spent on XR concerns. Possibly you’d prefer to compare with PS itself, rather than with all R&D? (a) I’m not sure how justified that is; (b) it still feels to me like it ought to be possible to capture some of the benefits from many of PS’s proposed changes; (c) my weak impression is that PS (or things similar to PS- meta-improvements to progress) is still less neglected, and in particular that lots of people who don’t explicitly identify as being part of PS are still working on related concerns.
