Well he's still sort of right. The 2008 shock was legitimately more intense than the 1929 one and we came out of it with a "mere recession" instead of the horrors of the 1930s.

This is largely due to what the US fed did in response (the US gov. fiscal stimulus probably helped some but not on the same scale). Luckily the fed was headed by Ben Bernanke, one of the most erudite scholars of the Great Depression at the time the world economy was hanging on by a thread.
