What I see in ARkNet is this...
1) Basically, a traveling facebook. You create an Ark. It follows you. Think about that for a minute. I have worked around college students for the past 20 years, and they would go gaga for this. "Raging Hormone Boy A" goes out to the bar on Friday and sees "Hot Chick B" across the room. Checks for an Ark, finds one, learns her first name & general interests, sees she is single. Walks up. "Hey Buffy, saw your Ark from across the room. I like parcheeze & B&D as well. Let's get out of here". Seriously, this would explode like FB, and for all the same reasons. This isn't "find out her name (somehow), go home, look her up on FB, etc." This is instant FB.
2) Your house is on fire! The fire trucks show up, but...how many people/pets are inside? An ARk the residents set up outside the home (and accessable only to fire crews), alerts them to the names and ages of those to rescue.
3) Municipal government. Your water bill? Property tax bill? Community events? Community notices? All in your "mail ARk". Result? Any time access, bill cannot be lost, proof of delivery, and not insignificant cost savings to municipalities.
4) Pet ARks. Create an ARk for your pet. If lost, it has traveling owner contact info, pet name, behaviour characteristics, etc.
5) is your car for sale? Put an Ark on it to show price, stats, maintenance history, price comparisons, and contact information.
I could go on and on and on. I am just spitballing here.
Two HUGE things to consider...
First, once ARks become more prevalent, do you think people are going to walk around looking at them through their phone all day? Nope. And this isn't Google Glass, where you are just looking at a computer through eyeglasses, basically. Your computer is on your phone and always with you. ARks are all around you...It is a whole other level of reality. How long do you think the "Hey, I wonder if that item has an informative Ark? Let me see the phone to check" phase is going to last before people start wondering "what ARks have I been missing by not looking"?
Second, as someone who does not use FB or Twitter, I can tell you this tech has become increasingly integrated into everyday social, consumer, and political life. ARkNet provides more than just voyeurism...It has serious economic and social benefit. Think that through.
VR is truly in its infancy. But there is no question it is one of the next steps in our technological evolution. $TTCM is worth what today, 60MM, give or take? That sound right for what they are bringing to the table?
I am 52. Up until a few years ago I taught college. 20-year-olds now have NO CONCEPT of what life was like before the internet. None. Five years from now, 20-year-olds will have no concept of what life was like before social media.
20-30 years from now, they won't be able to conceive of what life was like confined in a simple physical-only reality. One without VR.
