QT:{{”
The first to use the concept of a “singularity” in the technological context was John von Neumann.[4] Stanislaw Ulam reports a discussion with von Neumann “centered on the accelerating progress of technology and changes in the mode of human life, which gives the appearance of approaching some essential singularity in the history of the race beyond which human affairs, as we know them, could not continue”.[5] Subsequent authors have echoed this viewpoint.[3][6]

A quantum walk down Wall Street | The Economist

But on a closer look finance bears a striking resemblance to the quantum world. A beam of
light might seem continuous, but is in fact a stream of discrete packets of energy called photons. Cash flows come in similarly distinct chunks. Like the position of a particle, the true price of an asset is unknowable without making a measurement—a transaction—that in turn changes it. In both fields uncertainty, or risk, is best understood not as a peripheral source of error, but as the fundamental feature of the system.
