What struck me most was the originality of Lanier’s trajectory as a research pioneer. His technological trailblazing and vision have led to him sitting on the faculties and boards of big universities. But the book shows that a conventional academic career might have hindered him considerably. As he reveals with tales of his development of VR programming languages and the VPL experience, he carved out the freedom to follow his scientific curiosity, unlike many a postdoc or tenure-track faculty member. That is a useful insight at a time when technology research is thriving outside academia, as Google’s DeepMind and other technology companies lead the way in quantum computing, artificial intelligence, autonomous vehicles and, of course, VR.
