first of all 'nxt people' is wrong, as its a single person. he abandoned nxt long ago, when he moved on to crypti. so nxt was abandoned by berzerk. a forum mod, not a dev, not anything. i know it comes as a big surprise to you, but guess what, it survived! and just as a sidenote: i'm certain berzerk is still holding on to his nxt.

real world usage could be better, but its definately not non existant, like you're trying to suggest. there are a couple of companies utilizing nxt. compared to other 'altcoins' nxt has the most active forum there is. abandonment looks different to me.
in terms of technology: i suggest you install the wallet and see for yourself. its years ahead of anything else. but ill bite. why do you think nxt is a 'technological dead end'?

imo your post is a very poor attempt to mash lisk and ethereum copy and nxt together. whoever is paying you should invest his money in smarter people.
