... but we are on the way!! Even "Nakamoto" with his published paper in 2008 discerned that it's still to optimize. It's in its infancy but hey, I think the political/economic trends fuel developers to keep working hard for progress. In the end just the tiny bit of sophisticated ones will gain acceptance and win though, but as you said, still a lot do...
Absolutely agree! I think the major issue with the current market is that some people think that Bitcoin or other alt-coins will actually become used regularly, which is pretty far from the truth and leads to some bad investment expectations (e.g. Bitcoin has gone up X% in 2017, buy yours today because it will also go up by X% in 2018)
