Stop speculating. If you find a better opportunity then go. That is the way of the capitalist. The business is stagnant at best. Now is a good time to move if a stable opportunity can be found.
Stop for a minute and imagine where you want to be five years from now? Do you think qualcomm is even stable enough to be around in five years? Look at our product pipeline? Is the market big enough to bear marginally improved products to provide enough revenue to support your career ambitions at Qualcomm? Somewhere else?
Carefully examine the honest viability of revenue growth if you decide to leave or stay. Ultimately if people do not buy enough product at either choice, the prospects are grim.
It is wise to "follow the money" as they say but be sensible. Qualcomm will eventually be acquired or merged with someone.
Be honest and true to yourself but do not panic. That will only make thing worse
