Part of my story is set 50 years in the future, so...the year 2060-ish. My characters aren't there for long, however, but I have very little idea of how the world might be by then. Of course no one does but I have a few ideas and I want to be sure it's realistic. The cities are huge and have one acre of green land (grass, forest, flower bed, etc) for 5 square miles of city. There is still plenty of countryside which hasn't changed much but my bit in the future is in the city which is why building a good city setting is important to me. My MC is supposed to be able to see into some lower level flats and pass judgement on the decour...so far I have geometric shapes in clashing colours, which I don't particularly like but I want it to be different from the present and that was all I could think of. No one has cars run off oil anymore, they're all electric. The super rich have cars driven by GPS, although they can opt for a manual control. Long distance public transport is done in that method, with manual being used for entering/leaving stations. Short distance public transport is hover cars (some of the super rich may also drive a hover car) and by hover car I do mean something kinda like what is seen in the 5th Element but less...futuristicy, if you get me. Fashion has moved on...I'm thinking everyone wears neon colours. The brighter your colours, the more you've spent kind of thing so there's still a difference in social class evident. It's not entirely different from our time, however...the second time my MC meets the anti-hero (in his timeline it's his first meeting...) he is wearing jeans and a tshirt -and- to give them something to talk about it's a band tshirt (and I was very bad and gave my own name to the 10th album by a band I listen to and then killed the lead singer...) but it gave them something in common to draw them together. I have no idea how language may have progressed, but all I hear from people these days is 'reem' and 'beans' and 'yolo' so I was considering using things like that if it's realistic enough. I do want more than just that though =/ It is all set in Britain, I must point out as well...I'm working my head around the idea of setting it, officially, in Glasgow as I envisioned Suchiehall Street in my opening sequence but I haven't actually named any cities as such. The final thing I have, that needs a name rather than a reality check is a device which can change your body shape in 4 weeks. If you're skinny and programme it to make you buff, 30mins every day for 4 weeks you're exactly what you asked for. Or if you're fat want to be skinny, flat want curves...almost like home based plastic surgery but not quite as drastic, it's limited in what it can do and still a relatively new item in that time (and this is going to be in it because it's how my future character buffs up and there's a very embarrassingly awkward yet totally sweet moment where he confesses to my MC how he went from scrawny and geeky to h-o-t!). So, my question: how realistic are my ideas so far? Do you want to add anything?
