On “Nyquist Frequency”
Dan Worrall made a fantastic video which touches on Nyquist. His youtube channel is a tremendous resource: link to this video

Dan Worrall explains the science of audio sample rates, detailing when higher rates are beneficial, when they are not, and how oversampling works.
In this video tutorial, Dan Worrall explains when and why you should use higher samplerates for your recordings and mixing sessions, and more importantly... when you should NOT. Also, Dan goes in depth about oversampling vs. higher sample rates. More info about FabFilter Saturn: fabfilter.com/products/saturn-multiband-distortion-saturatio…Why it's here

On “Apple Music Announces Spatial Audio and Lossless Audio”
This is largely because MP3 is a crappy, old format. Try high-bitrate Opus on most samples and you're a lot less likely to get above-chance results on an ABX test, pretty much ever, at high bitrates. Ultimately though, lossy compression is always program-dependent ("program" here means the song, not the app). The encoders use psychoacoustic algorithms, and there is no way to prove they will perform well on all samples. So you will always be able to find corner cases where an encoder or format does worse and results in more audible artifacts; some of these might be encoder bugs, some might not. Therefore, it is fair to say that you might not want to rely on lossy compression for archival. But…

On “Why Cassettes?”
There is a bit more to that when we get to having to modify or convert audio formats, without "right" algorithms it might introduce some artifacts via aliasing link to this video
