"The glasses pick up audio and visual cues, translating them into text that gets displayed on your lens, right in your line of vision. These virtual subtitles overlay on your vision of the world, providing a contextual, USEFUL augmented reality experience that's leaps and bounds ahead of what the Google Glass was designed to do in 2013."

"Cathy Hackl: I think it's important to state that there is really no agreed-upon definition right now. Every morning-it's become a bit of a ritual-I go to the Merriam-Webster dictionary and type in the word metaverse. And every day it says this word is not in the dictionary. But if we needed to define it, I tend to have a pretty expansive view of what the metaverse is. I believe it's a convergence of our physical and digital lives. It's our digital lifestyles, which we've been living on phones or computers, slowly catching up to our physical lives in some way, so that full convergence. It is enabled by many different technologies, like AR [augmented reality] and VR [virtual reality], which are the ones that most people tend to think about. But they're not the only entry points. There's also blockchain, which is a big component, there's 5G, there's edge computing, and many, many other technologies. To me, the metaverse is also about our identity and digital ownership. It's about a new extension of human creativity in some ways. But it's not going to be like one day we're going to wake up and exclaim, "The metaverse is here!" It's going to be an evolution."

"Jaron Lanier, the author and inventor of the concept of virtual reality, warned that digital infrastructure was moving beyond human control. He said: "When you try to achieve great scale with automation and the automation exceeds the boundaries of human oversight, there is going to be failure. That goes for governments, for consumer companies, for Google, or a big insurance company. It is infuriating because it is driven by unreasonable greed. In many cases, the systems that tend to fail, fail because of an attempt to make them run automatically with a minimal amount of human oversight.""

"The ability to understand an individual's unique anatomic configuration from skin to bone can be a significant benefit to a surgeon, especially prior to a complex operation. Immersive VR will enable surgeons to explore their patient's virtual body-reconstructed from their CT or MRI data-and plan or even practice difficult surgeries prior to the actual procedure. "

"In the meantime, I actually like how most of these islands represent an attempt by education institutions to embrace the weirdness of the web. The current crop of education startups seem bland and antiseptic in comparison to these virtual worlds. I can't take a Coursera class on a pirate ship, or attend office hours in front of an edX campfire. And honestly, that's probably a good thing. But it makes the web slightly less interesting."

Project Tango is a prototype tablet that British developers made so that people can easily 3D map areas. I could see this as a privacy issue, do you?

"Virtual reality company, AVRT, has been collaborating with the force to create realistic computer generated scenarios officers might be in, such as dealing with a person in an alleyway or a rooftop"
