Here's something you don't see everyday, a frank discussion of the role that psychedelics played in the early years of NeXT software development. The story is being told by infamous NeXT developer Andrew Stone of Stone Design (Create, Twittleator, Videator—you can see the latter on the screen at TMO's Cirque du Mac Macworld/iWorld party), and it includes some of his personal observations about the emergence, growth, and eventual failure of NeXTStep and OpenStep, as well as stories about the Stone Rave parties held in the 1990s. Andrew Stone told his tale this week at AltWWDC in a presentation called DMT, the NeXT, and the Soul of the Human Machine, and posted the text at Stone Design's website. It's available as a video (starting at approximately 1 hour and 13 minutes). It's an interesting look back at an important aspect of what became the foundation of Apple's OS X.
