So I'm reading the book Does IT Matter by Nicholas Carr. His premise is that IT, like the railroads or other past technology innovations, gets to the point that because they are available to everyone they don't offer a competitive advantage and should be viewed as a commodity.
I think the difference between the railroads or the introduction of electricity and IT is that IT is continuing to evolve, and I'm not saying that just because I started a new job today with a software company. Successful companies will continue to take advantage of the latest innovations to stay ahead of the competitors. Companies in IT that want to stay in business will continue to find solutions to make customers successful.
