I personally think we are reaching physical limits at like 22nm>X>5nm. This is a big question that only patience can answer.

So what happens when we get to 1nm size processors? Well we get to the picometer. Is making a proccesor with a lets say 90picometer or 90pm process technology even possible? If so how long do you think until we start seeing them? Less than 5 years? 5 years? 10 years?

Personally, i think we'll see a completely new type of processor before we see a 90pm processor.
Oh, and, side note - moore's "law" is such bs. It's not a law at all, just speculation.

If you have a 5mm x 5mm die with 500 million 90nm transistors, you can either halve the process size to 45nm to get 1 billion transistors or you could just double the die size to 10mm x 10mm... Aside from heat and power consumption, why wouldn't that work?
