Damn! I had the impression that AE is working. Then what the f**k I just have bought and where...:O?!? I also got some dividends... so you say it's all just an illusion 
?
?What was fallacious about the statement was the "first functioning" part. Of course AE is functioning fine. I believe the true statement he posted was the fact that NxT was the first 100% PoS cryptocurrency. The rest of the claims are bogus.
For now, you are right. But my theory is that a PoS coin will seriously threat Bitcoin's leadership in the cryptocurrency world in the coming years. Bitcoin's transaction costs are pretty high because of mining, only that for now the price boom has "hidden" this fact. Now probably we are seeing the actual bear market as a consequence of the freshly mined coins being sold. Nxt and other PoS coins don't have this problem and thus can offer smaller transaction costs.
The lightning network will significantly reduce Tx costs on the bitcoin network, allow for instant confirmations, remove blockchain bloat, and allow Bitcoin to scale to Visa levels of TPS.
Look into it:

There are some really smart people working on it and it really isn't that difficult to implement (soft fork and some Tx malleability corrections that need to be done anyways)
