Billionaires and their crazy dreams, right? :D
But they can afford to bet on the wrong horse and then still pivot in time, or be well-positioned even.
At government + central bank level all around the world they are investigating digital currencies and here blockchain or similar in concept technologies are deeply investigated. Making a jump to that horse, supporting, becoming a dominant player can be twitter's future too. And attach an interop thingy from their own shop.
