Seth Godin revives the "end of the office" argument:
If we were starting this whole office thing today, it's inconceivable we'd pay the rent/time/commuting cost to get what we get. I think in ten years the TV show 'the Office' will be seen as a quaint antique.
When you need to have a meeting, have a meeting. When you need to collaborate, collaborate. The rest of the time, do the work, wherever you like.
The gain in speed, productivity and happiness is massive. What's missing is... someplace to go. Once someone figures that part out, the office is dead.
People have been trying to figure that part out for at least twenty years, and we've seem some changes in office design-- or at least the flourishing of a variety of new office forms that attempt to better facilitate collaboration, encourage creativity and cross-organizational work (two things that are often conflated, but are not the same thing, even if they're sometimes related), support drop-in and mobile workers, and so on. These aren't universal-- there's a reason Dilbert is still popular-- but they suggest a degree of resilience in the office that we'd do well not to underestimate.
