Project Xanadu: Even More Hindsight

Project Xanadu, Ted Nelson's visionary hypertext system from the 1970s, failed to achieve practical success despite its valuable concepts due to a combination of lack of design iteration, no compelling real-world use cases, and the severe hardware constraints of its era. The author reflects on attending a 50th-anniversary celebration of Nelson's work and learning from former Xanadu programmers that what appeared to be disappointing progress was actually hampered by extreme computational limitations—such as week-long compile times and minimal storage capacity—that made even basic development extraordinarily time-consuming.
