Re: Eternal growth
While your comment is spot on, you're ignoring that IBM lost is dominant status a long time ago. Technology and business changed faster than they could adapt, and the IBM way of keeping profits up has been so far an on going exercise of cost cutting actions that exchange short term benefits for long term survival.
On business of the IBM scale you can do that many, many times to keep these profits up, until there is nothing to downsize/offshore/layoff any longer. And IBM is approaching that point now.
