I only fully understood what Ethereum is all about when I got on with trying out Solidity and then had a good look at the Maker/Dai thing and DigixDAO. Bitcoin's limited, rudimentary scripting language is entirely incapable of interfacing with the real world in such elegant and fine tuned manner, and I am seriously beginning to think that there is a reason why they so stubbornly insisted on keeping it that way, while running mostly on aggressive propaganda, spam and advertisements....
