I was under the impression that not only did silicon memory double in capacity every two years, but magnetic memory also doubled in capacity every two years as well. This would make it difficult for silicon memory to catch up to magnetic memory. Unless, of course, you're really saying there is an upper bound on the amount of memory one can use...
