...those claiming they know how the system will be when it's finished are delusional.
Moderator Hint: Don't make it personal. Address the logic of the post, not the person of the poster. Do not attribute differing opinions to flaws of character or mental capacity, capabilities or altered mental states. That is pretty classic ad hominem. It is rude. It is rhetorically weak. If you don't need it to make your point, you shouldn't use it, and if your point is so weak you need it, then your point isn't worth making.
So, really, just don't. Thanks.
