I realize we are not done with it yet. There are new process node launches planned for the next few years and each processor generation continues to improve density, power consumption and price per transistor.

I’ll hold off declaring it dead till it is well and truly dead. And even then we could expect cost improvements as the great wheel of investment into the next node would no longer need to turn and the last node would become a final standard.

As to physical limits, there are plenty of weird quantum particle effects to explore so that seems overstated. We are still just flipping on and off electromagnetic charge. Haven’t even gotten to the quarks yet!

The classical Moore's law formulation has been dead for 15 years already. What we have now is whataboutism about why it still holds.

You can draw a straight line right through this log scale plot that goes to 2020. Not sure what definition of Moores Law you are using, but it doesn’t seem to match the one on Wikipedia.

well that is transistor count, not transitor per square centimeter which can't be measured because it is variable. the top chips are simply bigger

Here’s a chart for density. Still going strong with maybe a bit of drop off.
