I think pretty much all alts will die eventually. There's just no real need for them currently and without merchants getting behind them they're worthless as a currency. If one was to succeed then it'll likely be one that hasn't even been created yet.
No-one knows what will happen. It is entirely possible that everyone will have his own coin which functions like a extended CV, diary, private currency....... your live on your chain your money.
Of course it would not be a pow coin just like no government would make a pow coin thats where Bitcoin and not free produced coins are different, its a investment. Money itself is free.
