Junkspace: Is there a solution?

Koolhaas gives us a great picture of what “junkspace” is, however he never gives a solution to the problem at hand. How do we deal with “junkspace”? More importantly, is it possible to create architecture that does not fall into the category of “junkspace”? With the short lifespan of modern buildings we are creating junkspace faster and faster. However, with all of the shifts in technology, materials, and building uses of the modern age can we accurately anticipate the needs of a building that would be able to stand the test of time while still keeping up with “modernity” and thereby go past the junkspace label? I feel like today we are trapped in the cycle of building junkspace because very few people design to the future. Many designers today seem to design for the here and now, for the current trends, without giving a second thought to what will happen in the future.
