So...Elon had an idea, wrote it on twitter, didn't specify how it would work, and not only you're assuming how it will work, to derive these now highly ....hiiiighly hypothetical flaws of said unknown system, you're also click baiting that assessment with the key phrase "did he lose it?".

I don't know, is there no possibility of crowd-sourcing the rating of news according to its veracity? Is that what you're trying to say here? If so...man, that's kind of a bold statement. Specially considering the infinite amount of possible ideas the universe allows us...

But less on the philosophical/meta side of things, I'm not impressed with your performance on this one. It was a bit on the nose for something that is not even a thing yet.

Anyway, do I think it's a good idea. Yes! Absolutely! Do I think it's possible? Yap. But I'm not vouching for a twitter idea, of course. As far as ideas go, this one shouldn't even be considered an idea, just a sort of guide line for the actual ideas about its implementation.

So again, deliberating on the flaws of a system that isn't even a concept as of yet, it's as futile an endeavor as possible. Lets let the man come up with specifics and then yes, we shall deliberate on its flaws.

Cheers.
