Yann LeCun—LeCun faced backlash for attributing AI racial bias solely to training data, temporarily quit Twitter after exchanges with Timnit Gebru
In June 2020, after the PULSE AI model depixelated Barack Obama's photo into a white face, LeCun argued that 'ML systems are biased when data is biased' but that 'learning algorithms themselves are not biased.' Timnit Gebru and other researchers criticized this framing as reductive, arguing it ignores systemic issues in AI development. The exchanges became heated, and LeCun signed off Twitter on June 28, 2020, asking 'everyone to please stop attacking each other' and specifically asking people to stop attacking Gebru.
