People always say that remote working will be the way of the future, but humans remain extremely social animals. So much of what we do is guided by genetics and it seems to be human nature that if you don't see someone's face on a regular basis it is very difficult to create an intimate or trusting relationship.
This seems to be one of the main pain points when it comes to outsourcing work abroad, people seem to work best and collaborate the most when they interact frequently in person. In Pixar Story, I recall Jobs saying he designed the headquarters specifically for unplanned collaboration. As much as the world changes, people remain the same.
