In general I agree that these companies retract from the forefront and maybe aren't the innovative powerhouses that they once were, however both IBM and GE do fine as businesses and will probably be around for a long time. And I think it's important we have a bit of both in the world.

The new startups produce innovation and cutting-edge tech, but we need these huge monoliths for capital-intensive projects. Google has been a driving force in laying sub-sea internet cables across Africa and South America for a good chunk of time now, enabling billions of people to come online. I don't think a small company could achieve that since it costs billions of dollars to do.
