I saw Felienne Hermans give a talk on Hedy at Splash! but that wasn't recorded sadly, but here is a presentation too a much larger audience https://www.youtube.com/watch?v=j4eSjA6btE8 that I hope covers the same material.

It is a wonderfully amazing project. I don't know if the video goes into it yet, but when you see how truly egalitarian the project is, you are both proud and ashamed of humanity. Proud that Felienne made this project and all the lives she is improving, but ashmed that it took us this long. Lets make up for it by making everything we design with the same affordances. Lets democratize access to the future.

You might recognize Felienne from her research on Spreadsheets which I feel was a thing here around 2010 https://www.youtube.com/watch?v=0CKru5d4GPk It feels like that was the start of resurgence in respect for Spreadsheets.
