And we're discussing when to call it a failure. On a site called Hacker News. OK. But that's kind of my point - people can be so focused on "calling failure" that they miss the incredibly transformative development that's right in front of them.
Regarding a "timeline for calling failure" - who knows? Sometimes success comes to the sole believer who labors on long after everyone else abandoned hope. But how often in tech is something truly a failure? Was AI a failure in the 60's? It brought us LISP and defined the space. The 80's? It brought important foundational work to CNNs. The 90's? Would we be here without Deep Blue? Was mobile a failure with WAP? Palm? Newton? Was Internet 1.0 a failure when the bubble burst in 2000?
All were important steps that got us to our ubiquitously interconnected, AI-enabled, device-driven present.
So why the focus on identifying something as a failure, or tagging the moment that "they're not catching on"? How are you defining success? Adoption? If so, based on what metric - and at what ramp - and based on whose expectations? Investment success? For whom?
Even if this generation of VR fails to gain traction, I truly believe it will be viewed as just one more step towards the inevitable. It's that good.
But my point is that such failure will be due more to social issues than technical ones.
