The bottom line to the PoW vs PoS argument is that PoW isn't broken and doesn't need to be fixed. My car might get a flat tire, but I'm not panicking about it and trying to convince people that air-filled tires are just a disaster waiting to happen and the whole world is going to implode as a result of using them... So what if PoW has a long-shot potential issue? I might get hit by lightning, again, while simultaneously winning the lottery in 4 States at once, all of which I have never visited or even played the Lottery, but I still win as a token of wild chance that causes the wind to blow those 4 winning lottery tickets into my open mouth as I snore too loudly inside a dumpster in Harlem. My farts could turn into a zombie-causing virus that destroys the world. It COULD happen... Not likely tho...
