Gold did not die, gold has a rich history as well as a financial instrument and asset. Why was gold so? Because people believed in him, just as faith in bitcoin is being born now.
But let's remember why countries at the end of the last century abandoned the gold standard. Does anyone remember?
The reasons were as follows: the complexity of moving large sums, the complexity of issuing emissions, the possibility of losing a resource.
And here bitcoin solves 1 and 3 problem. Excellence on the face. Now we need to wait patiently, when the whole world recognizes the importance of electronic currencies.
True, gold still has a role to play in the finance world and probably always will. I wouldn't be expecting a gold standard to be restored anytime soon nor a widespread adoption in the case of a financial apocalypse, but I guarantee people will still be collecting and trading gold as a store of wealth. It's just not practical enough for daily transactions though.
Bitcoin is well on its way to solving these problems. We just need improvements in the transaction cost and speed (and efficiency in terms of electricity, a big problem until we do away with fossil fuels). Once that happens it will be more useful and appealing to investors.
