VR has been around for a long time, mainstream? I really doubt that, hey, I heard that email will "eliminate" the use of printers and paper...I rest my case your honor.
I never said VR will replace anything, I only said I might become mainstream once it's reduced to a comfortable size, barely noticeable.
Glasses will never be as comfortable as a fully functional 3D projector (if it's ever created), but at least there are people working on it.
"Email" hasn't eliminated the use of printers but has certainly reduced it. Nowadays you read the news online, when was the last time you actually spent money on a news
paper to read yesterday's news?
Finally, I just want to share a small episode from my life in 1997.
Me: "Dude!!! There is this new thing I found on the Internet, it's a new file format called MP3. You can save an entire song from a music CD in 2 floppy disks!!!! It's amazing!! This will be the future!!"
My best friend: "AHAHAHAHAHHAH!! Come on Bruno, that's impossible!! CD quality in floppy disk!! AHAHHAHAHAHHAHAH!!!! You're ridiculous! I'm not falling for that!"
Personally, the only difference I see between this and Google glass is the user software. And on that end, GG are way more fashionable.
For me, Google glass is way too ugly and intrusive. That's just my personal opinion, but I don't think it will ever go mainstream. This technology is way more sophisticated than Google's, at least graphics wise.
