First generation blockchains can't do much application wise, except store value. You can use side chains, but still the whole thing is slow, can't handle too many xactions, and is expensive.
Next generation blockchains are just so much more elegant in so many ways...
That may be so, but as I pointed out in the article, the market doesn't give a toss about that, proved by the fact that a Bitcoin is now around $3500. Maybe one day it will care, but not today . .
