Chips can be made that dwarf that limitation, instead we’re stuck with this decade old nonsense to “work around” again.
Flip flopping between “the code needs it” and “the chips need it”.
If you can process 512 then you get access to those, else you don’t.
Let the free market decide where it’s comfortable like it did with wireless security.
Free market decides where it lands.
If there’s nothing of value at 512, it’ll naturally flop.
