Not that I disagree with the underlying sentiment, but I just want to point out that this reasoning misses a significant bias:

Astronauts in general are super fit and healthy humans, in order to qualify as astronauts. It is wrong to compare them to any national average human life expectancy.

Great use case :) I actually also know somebody like that. Regardless of this though I am still quite sure with an issue like this, the devs at whatsapp would have simply cleared all the sessions, forcing all browsers to refresh without most people even realising it.

How can a web version not be rolled out to most people? If you refresh your web page it is updated - done. As the patch was released more than 10 days ago, surely most people had to refresh somewhere. Feels like just another sensational article to me...

Yes, I also just read that. Very misleading article and subject. The last paragraph says it only affects YouTube "app", so I feel it is a purposefully abuse of a catchy subject. At the uploader: Please change the subject!

Ah I see what you mean :) Yes that makes sense and I guess it will work, but as you said the magnitude might be too small to be audible.

Yes you are. There are no sound at all (or sound waves to be technical). It is basically just small vibrations that travels through your bones in your body, which your ears actually think is sound and then... magically you can hear! I guess you have to experience it to fully appreciate it. (I once was introduced to a phone for old people that used the same technology and it really works.) ps. Real sound actually also convert to small vibrations in your head before your brain interprets it, so this is just skipping the conversion step. Hope this helps :)

I wonder if a single electron ever poses a cap on progress in going smaller in technology... Although I must say time (given enough) always tends to eventually break through such limitations.

I would think the algorithm's heaviest weight would be on the ‘distance’. If so then strictly speaking a longer route increases the probability of accidents. Also if 'time constraint' is rather used, a route that takes a longer time, can possibly make drivers more irritated and thereby also impact accident probability negatively. Just some extra thoughts to also take into consideration...

So if I am trying to connect how would I be able to send any hash to any computer while I'm not connected?
