I just had some thoughts while working:
In the web, you can register at different websites for free. You get email-accounts, social network- profiles, blogs, webspace… how do they finance themselves? through advertising, premium-benefits and selling your data.
So why don’t people do the same in the offline world? We could rent flats without having to pay. In some way they would just include advertizing, say in the main hall of the building which you always enter, maybe they send advertizing by mail aswell, but otherwise you would have nothing to pay for living there and it could even be profitable for the landlords. Of course they could also include “premium” upgrades for your flat, so you might have more space, no advertising, elevators, better view, or something like that.
It’s not a vision of the best possible future, because I hate advertizing and everything being about profit. But maybe it would be a vision that’s possible to realize without chaning the world before and it would be a better option than having to pay for your living. Maybe I also did some grave mistake in my vision, you might point it out.
And, of course, it would be rather dytopian if landlords installed eavesdropping devices in your non-premium flats to sell all the data they collect of your personal lifes. I think this may not be possible legally, but it’s another intereseting comparison of how people would react to such behaviour on the one hand in the offline world and on the other hand in the online world (facebook).
If you got more ideas of how things could work inspired by how the internet works, you could also write them up here. Or the other way around. Another example would be to compare travelling with the internet connection. But I didn’t find any interesting idea there yet.
