The music industry has undergone a revolution that was on the verge of destroying it. In just over ten years, the public has stopped buying CDs and started downloading music. They have gone from possessing something physical that used to be collected and had a certain value to downloading intangible MP3 files that cost almost nothing. And the industry is beginning to adapt to this new situation, which has caused income to be generated from live concerts, subliminal advertising and digital royalties.

Architects are as baffled now as record companies were then. The bursting of the housing and subprime mortgage bubble has created a new scenario. What once had value and was secured by appraisers and banks has evaporated.

People are rethinking the need to own things, be it a home or a CD. The important thing is not to own something, but to enjoy it, and pay for it when you need it. Why store hundreds of CDs, if you can keep them on an iPod? Possession is a luxury only available to collectors and mythomaniacs. Enjoy the music you like and simply delete it when you are no longer interested in it. And this concept is moving into all areas, including architecture. Why do I need to buy a home if my job or my partner may take me to live in another city at any time? Why do I need a three-bedroom apartment if I live alone? If guests come, there are websites that will provide me with a spare room just a few metres from my house where I can put them up. Because the use of community resources is what the Internet offers. And that's more than saving. It’s sharing and creating a society that does not waste.

Music is 10 years ahead of architecture; let’s take advantage of its experience.
