That large part of the financial system is glorified and useless gambling designed to extract rents by intermediaries is a matter of record [0]. Regulators have no problem with that, provided their rather arbitrary and self-servingly generous red lines are respected.
So what is happening now is that new information technology (faulty and immature at best) is being used by cunning operators to tap into that ingrained behavioral pattern outside their purview.
Yet what spoils the fun is the sense that (somewhere in a parallel universe) all the new digital gadgetry could somehow be used to make our economies more robust, more functional, more equitable, more sustainable,... more real and less financialised.
