How come we didn't change much over 30 years?

Since back to the future day is coming (21st of October 2015), they imagined flying cars and a whole lot of green energy and fancy high-tech stuff.

And after 30 years, nothing has changed much. The only thing that is amazing are the Iphones and laptops. Apart from that, everything else is just a slightly better version of stuff in the past.

I think if people from 1985 came to the future they would be quite disappointed as they would either imagine a dystopian burned out buildings hell filled ghetto (Terminator, Matrix, Escape from New York) , or a shiny high tech future with tons of gadgets (Back to the future, Speed Racer). But in reality it is just as boring as it was back then nothing more.

This means that in 2045, we will be living basically the same way as now, with a few more gadgets.

Where are all the other answers to this so people can read what has been said. It is isolating, or is this done on purpose as if someone might give a good answer and they don't want anyone to read it. I do not like the new flipping set up. Something is wrong with the new design of this webpage. That is why you or anyone else is getting anywhere, It is being blocked from good use by idiots wanted to sabotage communications.

1 the laws of nature haven't been changed

2 People "making" money from the old techniques have ways to slow down the introduction of new green technology. Such as trying to convince you that Global climate change is not happening

Human nature doesn't change. It's still the same old story, a fight for love and glory.
