Your intuition is right on target, it will. In fact, I have been invited to give a talk at a conference in Barcelona a week from Thursday on exactly that point. Yes, from top will involve accelerators on the chip, more compiler activity to take advantage of it, and most of all additional microarchitecture to carry out (as always) what is dictated by the software. ...and this is the tip of the iceberg. Even without push from the "top," there will still be plenty we can do since we are not at all fully or properly utilizing the enormous number of transistors on the chip already. > Could you please > provide a little more insight on your views of how the industry will > progress in the coming decades? That one will require too long an answer to be really coherent. For openers, it will contain many processors interconnected, and many accelerators to carry out specific complex tasks which will then be done quicker than writing code to do it, and a serious interconnection network to enable quick access to get from A to B for all A,B. > For some context, I am actively trying to pursue graduate studies and > hopefully a career in academia.

Where work needs to be done: Everywhere. My advice is to learn about what goes on at all layers of the transformation hierarchy since they feed on each other, and your ability in one area is today (and more so tomorrow) enhanced by your knowledge in the other areas. Hope this helps. Good luck YNP
