What matters is the precision necessary and possible
With Fourrier transforms you can have as much precision as you need (and willing to pay for), and often more than possible with analog devices.
And hard drives actually illustrate my point: the analog electronics gone so far advanced as to be beyond the reach of any hobbyist, American or otherwise.
