Felienne Hermans, who seems to be leading this research effort, is also writing "The Programmer's Brain". It has a sort-of "early access" version that I've been reading as chapters have been coming out. From what I've read so far she has been doing her homework in terms of what science really knows about learning, memory and so on. What I really appreciate is that she also looks outside of the field of programming for answers to questions surrounding how learning and thinking "works".
If she has the same approach to Hedy (and I have no reason to doubt that) then I hope that the research being done with this project will bring in some new insights from outside of programming (and ideally also come up with some of their own, but I have a hunch that there's a ton of low-hanging fruit outside of the programming world that could be useful here).
