And 3nm CPUs, GPUs, phone SoCs don't have "real world impact"?

One could say they have an even bigger real world impact.

You do not need a 2nm processor to run an engine, perform an ultrasound, drop a missile on someone's head, make 10 million parts in a factory, or fly a plane. The vast majority of the increased processing power we've developed since the mid-2010s gets pissed away rendering 30MB websites or generating AI cheating fruit husband videos. Every phone SoC release for the last 10 years combined has done less in the real, concrete world we live in than industrial controls hardware from 30 years ago.

We can vibecode SaaS junk that we will have all forgotten about this time next year at never-before-seen speed, but every single day, hundreds or thousands of times a day, you brush up against something that was built by an AB or Siemens PLC installed in 2004 that might be slated for decommissioning in a decade or so.
