Regardless of what you think of the headline claim (edit: the link was originally "The next financial crisis will come from Silicon Valley," or something like that), the op ed does not argue it well.

Mt Gox isn't an example of a Silicon Valley company, much less a big enough institution to cause any kind of financial crisis. It failed with no effect on the greater economy.

Betterment and Wealthfront don't trade based on some black box machine learning AI. They just perform relatively straightforward tax-loss harvesting and rebalancing. Not HFT. Suppose all of their robots start making bad trades. The capital they manage represents a tiny fraction of the US market. It's hard to imagine that leading to a financial crisis.

Finally, ICOs have almost nothing to do with Silicon Valley fintech. They're just a classic scam dressed up in a new format.
