You're living in the past. Hard drives are now up to 36TB. Hard drives are always getting bigger. 47MB isn't worth worrying about, at all.
This is such a weird rationalization. You’d sell a kidney to be a 10x developer but making an app 1000000x smaller isn’t worth a thought? Maybe that’s why the former hasn’t happened.
While it is true that hard drives have large amount of storage, it is unlikely that are any Mac with a 36TB hard drive attached that needs to overcome WiFi time limit.
How far we’ve fallen.
