It might sound like this is possible because the human mind just isn't capable of imagining the mere concept of numbers this big, in reality it is impossible.
Human mind is definitely capable of comprehending very big / very small numbers with proper training, it's just that most people never really thought about those numbers. For average joe "big number" is a billion or a trillion, so when they hear that you can technically bruteforce a crypto key, they think that there's a chance like in winning a lottery, and some even try to bruteforce something or mine Bitcoin with their CPU. We should just explain to them that those chances are actually like winning a lottery billions of billions of times in a row, this number is so close to zero that for any practical purposes is should be treated as zero.
