It's pretty easy lol - IBM was also once an innovative giant. What worked then might not work now, the culture then might not be the same as the culture now,

It's pretty easy lol - IBM was also once an innovative giant. What worked then might not work now, the culture then might not be the same as the culture now, and the world then was different from the world now. The riches they have now are the results of the innovating they did 5-10 years ago. The next 5 years is a different question.
