Sadly it seems that not many people will given the current structure. Its only a matter of time until a coin comes along which copies the features they like from ethereum but offers much better investor terms, which would cause ethereum to languish ensuing shortly after. I want this coin to succeed, but as it is its model is similar to Freicoin, with a much stronger disincentive and I expect that the result will be the same and or worse regardless of the feature set. Satoshi was not just an expert in coding, but also an expert in human nature. Absent of the right incentive systems, even the most brilliant currencies will never take hold.
I think perhaps there will be a first year hump. Mining should also be ok. At some point ether adoption might outpace Btc adoption. Then switchover would be profitable. Agree, Satoshi's genius is shining through.
Btw, Ethereum is a brilliant concept. I want to invest in it too.
