I was just going to respond to the idea of algorithmic collusion.
The bigger issue, of which I think this is an example, is that we do not know how these algorithms are being used. That's all hidden and proprietary.
There are enormous financial market incentives for companies to take advantage of whatever they can about their data. There might be indirect collusion in terms of creating an environment where algorithmic amplification, reinforcement or however you want to go becomes quite powerful, but is still very opaque.
