First impression: Talk about a house of glass! ... For a second, I almost thought it was going to turn out that her clothes were made of it. (I should lay off the ecchi...)
[5]hoverboard or airtreks from airgear that can go up to 40kph atleast
Because everybody wants to stand on a board going 40km/h... And going in a straight line, seeing as attempting to turn on a hoverboard would make you smash your head into the ground.
Or going 40km/h on rollerskates which, if they hit a rock or edge, would also make you smash your head into the ground. Double thumbs up from me!
I see no reason you would fall on your face into the ground turning on a hoverboard any more than you would smash your head than into the side window turning in a car or fall off of a motorcycle doing the same. You adjust the sharpness of your turn based on your speed, and for something like a hoverboard or motorcycle you would lean into the curve, counteracting the so called "centrifugal force" by means of gravity. The drag might make it hard to stay on, though, since you don't have some kind of anchor like you would for a motorcycle. It never seems to stop people standing on plane wings or train cars, though, so meh.* Er, but that's not why I wanted to reply.
*I find it rather unlikely anyone could keep their balance on a train moving that fast, but I've never been there, so who knows. Standing on a plane wing is just plain silly, though.The question that's bugging me, and I mean -really- bugging me, is... where the HECK are they going to dig up that much SAND?! ... XD
Seriously, though... As far as the feasibility goes, I don't know if I see the technology for 2020, at least not to that extent, but talk of embedded displays in flexible, glass like material has been around for awhile. Really, really strong/durable glass isn't a new idea, either. It's horrible of me to say this without citing sources, but I remember reading articles about displays that could be flexed like a sheet of paper, with the potential intent being to use them as animated labels for grocery products (or some such rather silly "practical"* purpose). "Glass is fragile" as a stereotype just doesn't apply in a lot of cases. If all glass were so fragile that someone could just smack it and make it shatter, we wouldn't be using it like we are now.
* *scoffs* Imagine, using technology to do something practical. The fools! /jest
What I -don't- see happening is it becoming mainstream anytime soon after its introduction. I have to think that, with the price of screens still making it fairly impractical for the everyday user to line a wall with them, integrating display enabled glass at that level is simply not going to be affordable for quite awhile. A world of glass seems about as "near future" to me as Academy City. Heck, the latter even seems more plausible to me (sans magicians+espers, of course).
As for the robots a previous post mentioned, sadly I somehow see adult service bots becoming a reality before androids of that level. Whether or not we end up continuing down the road of human-like robots, it seems like it'd be easier to implement that than a robot capable of understanding human speech at the level that it could carry out more than the most basic of commands with any accuracy.* Maybe a basic command set, though. Voice recognition is apparently pretty decent, after all.
*Which would probably require a level of intelligence above and beyond that of an average human. -sighs sadly-
**C'mon, what's with all the bobbing up and down while walking? Why not maintain a constant elevation with rollers?
But I still don't think human-like robots are particularly practical. Flying or rolling around seem easier than walking, as well as most likely being more energy efficient.** And the human hand, as amazing as it is, could probably be improved upon for additional flexibility and/or durability. I'm thinking more R2-D2 than C3PO, as far as practical robots goes. Or Johnny, Johnny was pretty nifty.
Cyborgs sounds cool, though. Issues with magnetoflac* aside, I'd love an external computation processor** or enhanced skeleton, among other things.
*Orhwhatevertheheckitwascalled.
**Redundant?Disclaimer: I know absolutely zero about technology or the relevant science.Pre-edit: Can I "inb4 wall-of-text" my own post?
Edit: Grr... If I'm going to end up the top post of a new page*, I might as well go all out.
*It always happens.
With regard to the electric cars and adding in the infrastructure for powering them, the answer is obvious: flying cars and microwave radiation!
... It doesn't matter if the driver gets a little
sunburnt, it's the proof of concept that's important, right? XD
