No one expected Joseph Plazo’s TEDx session to dismantle the last remnants of the Wall Street mythos—but that’s exactly what he did.
Speaking through the lens of Plazo Sullivan Roche Capital, Plazo revealed that institutions quietly rewrote their execution protocols between 2013 and 2023, enabling machines to replace humans at every critical touchpoint.
1. The Death of the Trading Floor
Plazo began by describing how, a decade ago, traders still stood behind screens and made real-time decisions. Today, he noted, those decisions have been delegated to algorithms designed to operate thousands of times faster.
The Real Reason Humans Were Removed
He explained that emotion, fatigue, hesitation, and bias are liabilities in a world where markets move in milliseconds.
From Simple Bots to Market-Shaping Systems
Plazo highlighted how algorithms evolved from simple automated tools into entire ecosystems capable of liquidity discovery, sentiment analysis, arbitrage, and predictive modeling.
4. Retail Traders Are Competing With Supercomputers
Plazo didn’t sugarcoat it. Retail traders today unknowingly compete with AI-enhanced supercomputers that see liquidity, volume, and structure at a depth no human can.
5. The TEDx Message That Hit Hard
As Joseph Plazo concluded, he left the crowd with a message that resonated long after the applause faded:
“Human intuition isn’t dead. But in today’s markets, intuition must be paired with algorithmic understanding—or it will be crushed by it.”
His TEDx talk didn’t just explain the last decade of change—it armed the public with the truth behind modern trading.
And for many, it was the wake-up call they click here never saw coming.
