One of my favorite TED talks is this rumination on the increasing pace of change that Eddie Obeng presented in June 2012 in Edinburgh. His thesis is that for the first time in history changes to our environment are happening faster than we can process and assimilate them:

“We solve last year’s problems without thinking about the future.” –> this is the number one challenge for designing good products that can scale and remain sticky. You have to think of some future iteration of the product, then back into what that product would look like today and how it would address the problems you’re trying to address today.
