I have returned to be a bit more optimistic because of this article by Rick Falkvinge about the last Satoshi Roundtable. And my view of the most promising outcome would be a multi-blockchain world with BTC in a leading role. But for this to happen, there _must_ be a block size increase, at least a continous 10-20% increase per year, as well as off-chain methods like LN for microtransactions. If this doesn't happen, forget about BTC's leading position in some years.
