Nicholas Carr Wrote “IT Doesn’t Matter” Wrote “Does It Matter?” “Infrastructural technologies as I call them, open opportunities for forward-looking companies to gain strong competitive advantages.” “The opportunities for gaining IT-based advantages are already dwindling. Best practices are now quickly built into software or otherwise replicated.” “A safe prediction, I think, is that human innovation and creativity will continue; it is part of our very nature.” –Ben Bernanke
