Not everything needs cutting edge chips.

Heck, I can use crappy chips for every home appliance and home IOT device.

Sure I want high end stuff for my laptop so I can do AI, but that is just 1 application.

Yep. If you spend 5 years building a fab, then it will definitely be run on maximum utilization for as long as possible.

Things like microcontrollers thrive on the 180nm to 28nm nodes.

And even 74HC series logic chips are still being manufactured by Texas Instruments and Nexperia (former NXP/Philips). All fab capacity gets used.
