Some experts see that as a clear sign that  it’s reaching its end. Others that it’s already dead, because actually, the price per transistor has increased. Others that it’s physics, we can approach Y but after X nm it can’t be done.&lt;p&gt;Then you read others that claim that Intel has just been lazy enjoying its almost monopoly for the past decade and was caught off guard by TSMC’s ultraviolet prowess. Or people who really know how the sausage is made, like Jim Keller, enthusiastically stating that we are nowhere near  any major fundamental limitation and can expect 1000X improvement in the years to come at least.&lt;p&gt;Anyway, it’s really fun to watch, like I said. Hard to think of a field with such rollercoaster-like forecasting while still delivering unparalleled growth in such a steady state for decades.</text></comment>

CPUs aren&amp;#x27;t particularly large. My computer&amp;#x27;s CPU may be just a few tablespoons in volume. Hence, is compute less useful if it&amp;#x27;s spread out (e.g., due to communication speeds)?</text></comment>
