Mentioned by another employee in December, so yeah. https://twitter.com/CathyHackl/status/1205961097360093185

Page is up on his website, but no content there: https://www.nealstephenson.com/magic-leap.html

Oh man, I didn't know he worked there... It would be interesting to read a candid retrospective from him ... although in all likelihood that might not happen for years if ever.
