People (rightly) make the same critique of Bitcoin: it is very easy for regular people to lose their money. To keep it safe you need to be a security expert, and even then there are no guarantees, and mistakes are forever.

Almost no one can safely operate a printing press, and yet that invention has toppled empires. At worst, these are back office technologies. At best in a decade or two someone will figure out how to design a good enough GUI that a novice can safely explore a powerful subset the technology, trusting that bumpers are in place around the sharp edges.
