The vast majority of our contributors (especially our code contributors since we have a bit more diversity in the helping/doc/website part) are, to put it mildly, not very representative of the diversity of the world's population. In one of the sessions, Karen Sandler presented Outreachyhttps://www.outreachy.org/, a sister project within the SFC, whose goal is to provide internships very similar to GSoC, but for groups underrepresented in tech (with the notable differences that mentees can be non-students and can work on non-code projects). The main requirement to /enter/ this program (apart from the requirements we already match, be an opensource program, etc) is that to show dedication to the idea of increasing diversity, we have to provide ourselves the funding for the first student, which is $6500 (5500 for the student, 500 for travel, 500 for outreachy, iirc). From this first student on, we'll be "in" and outreachy's sponsors help outreachy make it work more like gsoc (paying the students working on projects)
I propose that we try to enter that program starting next year to try to build up a more diverse dev community.
