sure, if you don't have the slightest clue what quantum computing actually is.
That botnet can theoretically hash out stuff yes, but you aren't pooling that processing power, you are distributing it which causes it's own bottlenecks and headaches.
A quantum computer (they DO exist) can hash out faster than any of those combined. As well, through entanglement, the actual communication takes place over nothing, and is instant.
So, i mean while we can say QC may help break our current encryption, the technology that QC can eventually provide us will literally remove the need for encryption.
Unless you are at point A or point B, there's nothing to encrypt, listen to or steal. Spooky action at a distance is a real thing and it's spooky as fuck but potentially will change our entire techno-ecosphere for the better.
