The original comment was nothing about Burry. Burry is relevant because he did sucessfully make money off the GFC by spotting the issue. Barely: he was facing stockholder revolt over the fees involved in maintaining the position, even though it resolved.
Which is the point: the market can (generally) remain irrational longer then you can remain solvent. Even when you're right.
The stock price today may be a bubble, I don’t know. But Burry’s comments were before the current run up.
