I often read, in widely published and observed articles, and 'reputable sources' etc. e.g. this one: https://www.sweetwater.com/insync/7-things-about-sample-rate/. claiming that sample rate is somehow correlated to the audio frequency spectrum and that since humans don't hear above 20khz there's no reason to strive for high sample rates in music recording.
As I understand it, a sample rate is the speed at which an ADC or DAC pulls or renders packets of audio information as defined by bit size from or into an audio signal. In the case of DSD the packet size is one bit hence the high sample rate.
A sample rate of 1hz at 1bit in my understanding would only be able to pull one (or two?) bit of information every second. Therefore a faster sample rate with a higher bit depth is always more desirable -- in the case of a discrete function pulling from a continuous source of information -- the higher the sample rate and bit depth, the more information get's pulled or rendered. That said there is a threshold in my experience where the benefits of higher sample rates are imperceptible, although that's to be determined by the listener. And furthermore as far as I understand, I'm unaware of any correlation between this perception of quality and the fact that the upper human hearing threshold is ~20khz.
A 44.1khz 24bit recording should roughly equal the resolution 1.056mhz 1bit DSD recording right?
This article touches on some of the points which I may be confused about:

In any case I'm hoping to better understand the relationship between perceived audible frequency and sample rate if there is one.
