By &quot;in its current form&quot; I mean whatever growth &amp; developments have been implemented in the industry since 2009, and to a lesser extent since 2011.<p>I&#x27;m not an insider or an expert, and I&#x27;m sure there are many nuanced arguments for and against individual use cases.  I&#x27;m really just trying to point out that there it is not clear what the systemic risks are, or how algorithms will behave in a market that is drastically different than the what we&#x27;ve seen in the last 4 years.  It is impossible to test a system like this as a whole.  My personal lack of knowledge about the inside baseball does not change this fact.  And dismissing the macro view because of nuanced micro arguments comes off as flippant, elitist, irresponsible, and incorrect in my opinion.
