I disagree with this sentiment. Form factor has been the driving force behind the adoption of computing devices throughout history—look at the PC or the smartphone. Each one marked a new era. Glasses seem like the preeminent form factor for a computing device, short of a direct neural interface.
The smartphone enabled always-available computing. Glasses will enable always-on computing.
AR has a ton of mostly-work-related uses - think about warehousing, quality control, maintenance and repair, recording first-person views for tutorial videos or live seminars, identifying plants, HUD during surgery, schematic displays while working with electronics or mechanical parts, and many more.
For leisure the only thing I'd want a display on my face for is reading books and news.
