Wall Street has been using the most + most hopped up computers for a while.
Clearly it's the case, that a large enough "system",
can place an order for a few of the new shiny supercomputers,
and the dudes at the other end ~could have no idea,
that it was a computer that ordered the computer.
They can be duped every once in a while, sometimes by each other.
The
Flash Crash is an example of this. Poor uncle fester lost his Bentley on that one ...
Most of the manufacturing + shipping is automated now.
The human element, of the giant tonka truck diggers,
that get the rare earth elements, out of the ground,
is less and less every year.
Intentionally so.
