They will keep watering dead flowers until it seems to work. Just look at the Gartner's hype curve of this year: almost nothing is going on in short, everything is stuck, mostly because of lobbies/regulators (working against innovation, like against AirBnB, against Uber, and so and so). When all of that waiting innovation will go popular, the tsunami will be even worst: almost every area of economy will be disrupted. People which is doing lobby against innovation is turning a slow change into an apocalypse.

Also, the more derivatives they do, the more risk they have about panic: currently, there are derivatives for an amount which is ~50 times the planet's whole GDP. Which means, if just 2% of owners decides to go back to cash, there is not enough value to cover. If they produce even more derivatives, let's say 100 times the world GDP, the risk is that 1% of people wants to go back to cash. So a little fluctuation can cause a disaster.

Is just a matter of time.
